Run SIMO Condition

Run a SIMO condition from a task file.

Demonstrates importing a SIMA task file (stask) and running a specific condition using the SIMA Runtime Engine (SRE).

Requirements:

• Environment variable SRE_EXE which points to the SIMA executable

• Input file: ‘input/simo/simo.stask’

Example

>>> python run_simo_condition.py

main()

Run a SIMO simulation condition using SRE.

Imports a predefined SIMA task file and runs a specific condition. Clears the workspace before running for a clean execution environment.
