<p>Maurice,</p>
<p> As soon as you call the TRNExe64.exe, it calls the TRNDll64.dll
so I don't think that the communication is going to get any faster
since Trnsys is already a dll. The *.exe part of TRNSYS is mostly
occupied with the online plotter so if you get rid of all the
Type65s in your simulation it will run a bit faster. However, if
you have already used the /h switch then that is about as fast as
it is going to get.</p>
<p>kind regards,</p>
<p> David</p>

<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>
