<p>the FMU is 32-bit and does not work with the 64-bit version of
Trnsys18. A 32-bit version of Trnsys is available. You can contact
your distributor if you want to explore that option.</p>

for your reply. I installed Python32bit on my 64bit system

errors that could not be solved at the end. By the way, my
TRNSYS version is 18, does the FMU tool work with the 18

any alternative way to speed up the co-simulation between

<p class="MsoNormal">The generated FMU should work on
Windows 10 without problems.
</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Most likely the issue is the
compatibility of the generated FMU with the Python
version you are using. Because TRNSYS 17 is a 32-bit
application, the FMU’s binary is also a 32-bit. For
this reason, you will also have to use a 32-bit
version of Python, otherwise the FMU import will not
work.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am not sure if there is a pyfmi
version available for 32-bit Python. An alternative
would be to use an older release of Python (version
3.6) and package fmipp (version 1.4, see [1]) for
importing and handling the FMU.</p>
