With eddy3D, I tried to do my wind analysis work but errors are keep occur.

What’s the matter with that?

1. The mesh folder C:\Eddy\Project01\0\constant\polyMesh is empty. Can’t retrieve probes from a mesh that does not exist.

With AI(chat GPT, Claude), they said that I have to deal with the component ‘blockmesh’ but there are not in my grasshopper library. And I even tried forced file creation.
