Hii,
I am trying to subtract a STL file produced in Blender from a Brick created in Cubit to create the fluid domain which I will mesh later.

I have complex geometry (bird) which I have sculpted in blender. I tried different meshing softwares GMSH, Salome and now Cubit. GMSH has problem importing them. Salome imports and boolean operation works but I am not sure how to implement the blocking strategy for that. Moving to Cubit, import works but Subtraction fails with the error.

ERROR: Performing SUBTRACTION with volumes containing geometry
from different modeling engines is not allowed.
Delete uncommon geometry on these volumes before operation.

Any help on the topic would be very appreciated !
