DesignModeler uses Parasolid, which is limited to a modeling size of 1000 m cube so geometry must have a coordinates < 500 m.
The geometry you have in Rhino is 40 km along the long edge. What do you intend to do with this geometry?
Enable Large Model support to use a larger size. The modeling size expands to 1000 km.
The tradeoff is that the modeling precision goes down from 1e-8 m to 1e-5 m.
One thing you could do is scale the geometry in Rhino by a factor of 1/50 so the 40 km length becomes 800 m. Then you can mesh. If the mesh is going to Fluent, you can scale the mesh back by a factor of 50.

Thank you very much for the comments.
I study on tectonic deformation. The solid is part of the earth's crust. Therefore it is large.
I already activated large model support. Otherwise, the model can't be imported to Ansys.
Can I scale in the mechanical apdl? If it can I will try what you said.
Best Regards

I don't know how to scale a mesh in MAPDL. I only read that it was possible in Fluent.
You don't need a perfect edge match, you only need the mesh to be congruent at the boundary.
