<p style="margin-top: 0px; margin-bottom: 0px;">Maurice,</p>
<p style="margin-top: 0px; margin-bottom: 0px;"> I have not used Python, however, TRNSYS can be called from the command line so I assume it would be able to be called from Python as well. The command line to run one of the TRNSYS examples is:<br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;"> </p>
<p style="margin-top: 0px; margin-bottom: 0px;">c:\Trnsys18\Exe\TRNExe64.exe "c:\Trnsys18\Examples\Calling_Contam\CombinedThermalAirflow_AHU.dck"
<br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;"><br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;">if you add a /n at the end of the line then there will be no need to click "ok" when the run completes.</p>
<p style="margin-top: 0px; margin-bottom: 0px;">if you add a /h at the end of the line then TRNSYS will run entirely in the background.</p>
<p style="margin-top: 0px; margin-bottom: 0px;"><br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;">kind regards,</p>
<p style="margin-top: 0px; margin-bottom: 0px;"> David</p>
