SysML model transformation to Simulink and Modelica
19.0 sp3 version allows users to export standard SysML models into Simulink (incl. Stateflow, Simscape) and Modelica models based on a standard mapping provided by new OMG SysPhS specification (SysML Extension for Physical Interaction and Signal Flow Simulation).
This one-way transformation supports both black-box or full implementation which includes parametrics, statemachines, internal structures with ports, interfaces and connectors.

Simulink Import
The SysML plugin has undergone some major improvements. Simulink model files can now be imported and represented as SysML Blackbox Blocks. Once the file is imported, you can select input and output ports to be represented as Flow ports on the Block. Additionally, the imported Simulink model can be simulated using the Cameo Simulation Toolkit.
Enhance your modeling experience – contextualize Allocate, Refine, Satisfy, Trace, and Verify relationships to consider the context the connected properties are used in. Beginning with this release, users can more easily create and keep contextual relationships up to date in diagrams and matrices.

Pins for the Opaque Actions can now be created automatically. Learn more >> Image Added
Starting with this version, you can create Item Flows in two modes:
Direct
Between Part Types
The Direct creation mode allows you to create the Item Flow between ports or parts in the SysML Internal Block Diagrams.
The Between Part Types creation mode allows you to create the Item Flow between Part Property types. In this mode, you can quickly realize and synchronize Flows on Activity Edges, Connectors, and Messages.
The new Item Flow Manager allows you to analyze and manage the Item Flow data. Using the Item Flow Manager, you will be able to:
Edit existing Item Flows by adding new Conveyed Items.
Realize or hide existing Item Flows on selected relationship.
The Select In Structure Tree and Open in New Structure Tree commands are implemented. Now you can navigate from the elements in the Model Browser to the Structure tree or open the selected elements in the new Structure tree easily.
Key issues fixed
The issue making it impossible to launch the Networking Diagram due to the missing diagram descriptor has been fixed.
The issue concerning the inability to invoke the Parametric Equation Wizard as a result of the frozen modeling tool has been fixed.
Product Line Engineering has been significantly extended by implementing the Model-Based Product Line Engineering (MBPLE) capability. In addition to integration with PLE tools (Big Lever Software Gears and Pure Variants), it is now possible to perform PLE in modeling tools without using third-party tools.
We are proud to introduce the brand new ISO 26262 Functional Safety Plugin. This plugin tightly integrates functional safety with MBSE (requires SysML plugin or Cameo Systems Modeler) and supports the ISO 26262 standard (the adaptation of IEC 61508) designed to comply with needs specific to the application sector of Electric & Electronic (E/E) systems within road vehicles. The ISO 26262 Functional Safety Plugin provides end-users with the means to perform hazard analysis and risk assessment:
Define Malfunctioning Behaviors for each Function
Specify an Operational Condition Library
Define Operational Situations as a combination of Conditions
Combine Malfunctioning Behaviors with Operational Situations to define Accident Scenarios
Specify a Hazard Library
Define System Level and Vehicle Level Effects
Combine Hazards, Effects, and Accident Scenarios into Hazardous Events
The plugin also provides a way to define functional safety concepts (safety requirements and perform ASIL decomposition) as well as generate safety reports.
Image Added
A HARA Table allows you to define Hazardous Events as a combination of Hazards, Effects, and an Accident Scenario. The description area shows all the information about the selected Hazardous Event.
Modelers now have more freedom to decide how to organize elements in tables. Simply choose one of the tree-view options to display elements hierarchically and see the changes in the table structure reflect the criterion you have specified:
• Containment: displays
Managing Resource Locations
Resource/Plugin Manager on Premises
The Resource/Plugin Manager now enables you to deploy resources located in a file system, network share, or a web server within the company premises. It is now possible to host resources and plugins (built by you or No Magic) within the company premises so that you can manage upgrades of the desktop client resources/plugins in a controlled fashion.

Deploying resources located within the company premises
Matrices now satisfy the most sophisticated modeling needs. You have the freedom to specify the criterion for building a custom Row/Column hierarchy tree in matrices, using one of the following tree view options:
Select Containment to display
the decomposition of elements related by Containment.
Select Structure to display
• Structure: displays the decomposition of Part
Properties
properties related by Composition.
Select
• Custom
to display
: displays the decomposition of elements related by any specified criteria
In the latest version of our modeling tools, model validation and metrics work together, allowing you to quickly understand which elements are behind validation-based metric values. Metric creation will be much easier, because you can reuse existing validation rules to calculate them. Additionally, a Metric Table can be used as a dashboard to track validation results and analyze them over the course of time.
Image Removed
You can display failing elements for a particular metric cell with just a few clicks.
Suspect Links
Stay up to date with the changes in your model by enabling the Suspect Links tracking. You can now track the changes applied to requirements linked to other model elements, as well as keep track of the changes that affect the selected model elements at the chosen end (source or target) of the specified dependencies.
We put a strong focus on usability when developing new features. From now on, all elements with an active navigation target (either set automatically as the default according to a predefined set of rules or specified by the user) are depicted by an icon. Consequently, the navigation in diagrams has considerably improved.
Your complex model and nameless elements will no longer prevent the rapid creation of relations between selected elements. With the completely redesigned Create Relation dialog, you can now create relations by simply selecting the desired ends in their exact locations: a Model Browser, a diagram pane, table, relation map, or a dependency matrix.

Assigning Keyboard Shortcuts Using the Redesigned Keyboard Panel
Further Improvements
Now you can create nested structures quickly by pasting structural lists on Composite Structure and Internal Block diagrams. Image Added
To quickly create Activity Actions you can simply paste a copied list from any source of information. The Actions will be created and connected. Image Added
ReqIF import/export has been improved as well. From now on, all existing images are attached to the model upon ReqIF import and added to the ReqIF file upon export.
ID prefixes no longer come with the applied HTML styles. Instead, all IDs are imported/exported as plain text.
It is now possible to specify the element properties to be shown on the shape by default in a few clicks.
You can now wrap long text into multiple lines to display all of it in a table cell.
The modeling tool now allows entering an unlimited number of entries into the table cell to enable displaying multiple values/plain text lines in a table cell.
To save time, you can now create multiple relationships in matrices simultaneously. Image Added
The redesigned Documentation property group in the Specification window allows you to have all comments annotating model elements in one place as well as create and manage them easily when needed. Image Added
For your convenience, the Keyboard panel has undergone an extreme makeover. You can now manage and assign/unassign shortcuts to modeling tool commands more conveniently.
You can adjust active diagram zoom controls using the updated Zoom Slider Component, located on the Status Bar.
When you drag and drop a classifier onto a control flow, the control flow is converted to the object flow with corresponding pins and type of pins set to the dropped classifier.
Dragging a property from the Containment tree onto another property in a diagram redefines/subsets that property.
Dragging an element onto a Note or a Text Box creates a reference to that element.
You can hide the icon shown before the name of the element in the compartment via the Symbol Properties menu.
You can use the Symbol Properties menu to enable the Show Derived Sign property to mark (/) all derived properties in the Tagged Values compartment.
Custom diagrams can be created from already existing diagrams with a few simple clicks in the Customize Diagrams dialog.
Using the Customize Generic Table Wizard, you can easily specify the desired properties and create custom Generic Tables.
Using the Customize Relation Map Diagram Wizard, you can easily specify the desired properties and create custom Relation Maps.
For more intuitive workflow, we are introducing shortcut menu in the Used by and Depends On panels.
If your modeling tool uses too much memory and/or you see the Out of Memory errors appear, you should try dumping the memory heap. You can now do this using the Memory Monitor or by running the submit_issue.exe file packed with the modeling tool.
For compliance with the UML specification, a Behavior is no longer automatically set as the Classifier Behavior of the owning Class when it is created as a Method. New validation rules have been introduced to ensure that a Classifier Behavior is not used as a Method and vice versa.
Know your changes - Used Project Update Impact Analysis
The used project update impact analysis minimizes the risks of introducing unexpected and unwanted changes to the main project. Previous tool versions required you to switch used project versions pretty much blindly and hope for the best. Most of these blind updates caused main project composition integrity errors, such as recovered elements. Solving these errors was extremely frustrating and a time-consuming task. Thus, we created a new feature, providing you with early insights into the impact a used project version switch brings to the main project. You are then have the freedom to easily accept, reject the changes, or choose a different target used project version altogether.
You can use the analysis to inspect impacting changes at different granularity levels, allowing you to see the impact on element-to-element usages or to dive deeper into specific affecting/affected element properties. Differently colored changes allow quickly distinguishing between addition, modification or deletion changes. We are sure the used project updated impact analysis will deliver the value that comes from early change insights and better decision-making experience in general.

Since merging itself is a relatively complex procedure, requiring deep understanding of model changes, in this release we deliver multiple enhancements oriented towards better UI usability and change analysis flexibility:
Merge Result Preview, column filtering. Ever felt lost because you are not completely sure what kind of element changes the final merged project will have? The new Merge Result Preview column lets you inspect final changes at property level changes before merging is complete. Additionally, as we introduced a new Merge Result Preview column, we added the ability to show/hide selected columns. For example, by default, we hide the Ancestor column, to prevent confusion when there are no conflicts. However, you can select to show Ancestor again, in case it is needed to solve conflicts.
Change presentation and filtering.Are you tired of always expanding the element tree to find a wanted element? From now on, all changed elements can also be represented in the flat list-view. Furthermore, use a search bar to find the exact name of the element you want to check. You say that this small feature is no help where there is a number of similarly named elements? Another enhancement, change filters, will come in handy. Change filters are introduced not only for the flat list-view but also for the tree-view. All change filters are presented in one categorized menu.
Accept/Reject changes improvements. Work even smarter with the improved Accept/Reject buttons. We have combined the Accept/Reject buttons with the Go to next button. Easily go through all changes with a combined action and no more wandering around the Merge dialog, going back and forth to select and accept/reject another change. Furthermore, the specification panel was enriched with the ability to accept/reject property changes directly via a shortcut menu in the selected contributing column (Source or Target).
Locking elements prior to modifying them is now a thing of the past with the introduction of the Lock-free model editing mode (a.k.a an optimistic locking). You can continue using locks if that is what suits your team’s needs best; however, the Lock-Free editing mode is a simple yet effective way to boost modeling productivity.
To start using the Lock-free editing mode, first enable it in the project, after which you can work on model elements freely, without locking them. Consequently, there is no need to wait until locks are released by other users to work on the same or related parts of the model. If conflicting changes occur, you can handle them in the Conflicting Changes panel to prevent data loss.

Handling conflicting changes in the Lock-free Editing mode
The Disconnected team collaboration UI has been rebuilt from the ground up. The improved feature usability allows distributed teams working on the same server project to update it with the changes from the locally exported .mdzip file more conveniently and with a significantly reduced amount of manual steps.
Not only can you now update projects without having the target ones open in the modeling tool, you can also manage used project changes more easily. Additionally, the newly-implemented smart branch selection algorithm ensures configuration-aware update of server projects and smoother project merging in the future.

Updating a server project from a local .mdzip file
Along with improved Merge usability and bug fixes, the 19.0 SP3 release adds adjustments to common ancestor calculation algorithm rules. As a consequence, subsequent project merging iterations can be carried out more effectively without the need to repeat previously made merge decisions.
For your convenience, we have moved an environment option Support Mount Points of Usages in Teamwork Cloud from Save/Load to the Collaboration node. Image Added
When working with change sets, you can now discard both suspended and all local changes in an active change set. Image Added
The Maintain Mount Points of Used Projects option can now be accessed even more conveniently. It has been added to the Update from Local Project and Add Project to the Server dialogs. Image Added
Indirectly used projects can now be hidden or unhidden automatically together with directly used projects when their status changes, such as upon the used project update, remove, or merge.

Other Enhancements
Together with the used project update impact analysis, we introduce a Used by Project shortcut menu for quickly reviewing how the main project uses elements from a particular used project.
We are introducing an advanced memory tracking mechanism. This mechanism will track and notify you when the tool is running out of allocated memory, and suggests that you revisit your Memory Settings.
The implemented detailed project statistics feature calculates whole project statistics and exports results to a separate file. This is a quick and easy way to provide statistics to the support team when dealing with issues or share them internally for your own needs.
For a better user experience and more intuitive workflow, we have introduced shortcut menus for common project usage-related actions in the Project Usages dialog.
For security matters we now hide TWCloud project categories in the modeling tool dialogs if a user does not have Categorize Resources permission or Read-Only permission for at least one project inside these categories.
The new template.docx.ignorechildstyle report property for the DOCX template is now available for ignoring template styles to be included into generated reports and applying matching styles in the main template instead. Learn more about this report property >>
