I installed Butterfly 0.0.05, blueCFD-Core 2020-1, with Rhino 6, 6.34.21034.07001.
I got the error as shown below when I run blockMesh. Anyone could give a help?
Just solved the problem by re-installing another lower version of blueCFD (2017-2 ).
Hopefully this can help people with the same problem.
Thank you so much! It finally worked!
