Note

title	Prerequisites

Before starting the simulation, make sure you have prepared your environment and projects for server-side simulation as described in the following topics:

Preparing the environment for server-side simulation

Preparing projects for server-side simulation

To set up Jupyter Notebook

...

In Jupyter Notebook, run the following command to install a Python package from the
pyST.zip file located in the modeling_tool_installation_directory
<install_root>\plugins\com.nomagic.magicdraw.simulation
directory
\pyST.zip file:
Code Block
%pip install pyST.zip

Code Block
%pip install pyST.zip

...

The following table describes the parameters used in the request:

Parameter	In	Required or optional	Description
server_host	path	required	The Teamwork Cloud server host name.
server_port	path	required	The Teamwork Cloud server port.
TWC_user_name	path	optional	The Teamwork Cloud user name. If you do not specify the user name in the request, an input field will be provided to specify it later.
TWC_user_password	path	optional	The Teamwork Cloud password. If you do not specify the password in the request, an input field will be provided to specify it later.

Tip
For instructions on how to run server-side simulation using SSL, refer to Running server-side simulation with SSL

The following table describes the parameters used in the request:

Parameter

Required or optional

Description

project

path

required

The Teamwork Cloud project name or ID.

version

path

optional

The Teamwork Cloud project version.

branch

path

optional

The project branch name or ID. If the branch is omitted, the trunk is used instead.

element_id

path

optional

The server ID of the Instance Specification to be executed.

config

path

required

The Simulation Configuration name or server ID.

auto_start

path

optional

Starts the simulation automatically after the initialization phase is completed. Available values are:

- true (default) - performs the initialization phase and then starts the simulation (the simulation clock is started).
- false - only the initialization phase of the simulation is performed. The simulation then waits for an invocation to start the simulation, do a step, or terminate the simulation.
  Note
  The ?autoStart query parameter is ignored when multiple iterations are running, e.g. Tradestudy, Montecarlo, or table simulation

commit_results

path

optional

Commits a new project version with the simulation results. Available values are True or False (default).

verification

path

optional

Returns the selected verification results. Available values are:

- All - all verification results are returned.
- None - no verification results are returned.
- Fail (default) - verification results with the fail status are returned.

data

path

optional

A set of output parameters, which will be obtained after the simulation is complete.
