Running TRNSYS from Python

The Python subprocess module makes it easy to run external programs.
TRNBuild, Simulation Studio and TRNSYS can be run from the command line.
So, you can use Python to run a series of TRNSYS operations at once.
The following example shows how to run a multi-zone model in Python.
- Generate VFM and SHM/ISM in TRNBuild
- exporting a Dck file in Simulation Studio
- run TRNSYS.
This may not seem to be a popular use, but it may be useful in cases where the calculation is repeated over and over again.
