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.
