Save volume mesh as f3grid file from Rhino using griddle

Griddle

Dear all,

I’ve generated a volume mesh in Rhino using Griddle. However, I’m facing challenges when trying to save this mesh as an .f3grid file for FLAC3D. Each time I attempt to save, it defaults to a different format. Any assistance would be greatly appreciated.

Thank you.
