BlockMesh fails in Grasshopper searching wrong path (C:/ instead of D:/)

grasshopper butterfly

Hi,
I have an issue when running any mesh block (blockMesh) from Grasshopper using Butterfly on Windows. When I run the block mesh I recive the error:
FOAM FATAL ERROR: cannot find C:/Program Files/blueCFD-Core-2017/system/controlDict
But when I run blockMesh manually through the BlueCFD-Core terminal, after navigating (cd) to my case folder on the D:/ drive, it works perfectly.

What I’ve tried so far:

  • Running Rhino as Administrator
  • Modifying paths in runmanager_bluecdf.py to point to my D:/ case folder
  • Moving the project to C:/ (did not help)
  • Confirmed the case folder exists

Anyone has any tips in how to get Butterfly/Grasshopper to run OpenFOAM commands with the correct working directory?

Thanks,
