I have tried to install the molecular addon on windows 10 and ubuntu 18.04 on blender 2.74 and 2.79 and rebuilding the 64 bit version of cmolcore (succesfully) through the scripts provided in the github source but cmolcore is always undefined upon trying to run the molecular simulation. The older release files work but they arent the newest versions and are more cumbersome to work with, and the newest source code doesn't work. I am a a loss as to what the problem is and have searched for a solution but installing Visual Studio redistributables and downloading releases from the pyroevil site (which is down) doesn't work.

  • $\begingroup$ even though this problem is about blender, I think Stackoverflow is more likely to answer that question, since there are more devolopers. You could also try and contact the developers...? Anyway, it would be much appreciated if you post your solution as an answer here when you found one. $\endgroup$ – HenrikD Jul 21 '19 at 7:38

The molecular addon created by Pyroevil has not been updated for several years.

You can find a couple of forks of this addon, the one by scorpion81 has been updated to work with 2.80 and also has a branch for 2.79. There is another fork by PavelBlend that has more recent changes. Both of these offer some pre-built copies of the addon from their releases page. If you get a git snpahot of the addon then you will need to compile the addon to get it working, you will need cython and a c/c++ compiler for that.

If you have no luck with these forks, you might want to report an issue to one of these projects on github to see if they can help you.
