The error message suggests that some domains in your geometry are not meshed.
I've seen it a few times that a user will mesh the faces of a domain (with triangles or quads) instead of meshing the domain itself (with tets or bricks or prisms). Perhaps that's what's going on with your model?

Perhaps your file is too large. Use "Clear all meshes" and "Clear all solutions", then save as, and try attaching that smaller file to this thread.

I meant the .mph file. Screenshots are rarely useful in figuring out what's wrong in a model.
