Trouble importing geometry to CFD

[Anonymous]

I made an assembly geometry on CAD, I tried to import it on different format.

I got the same problem each time the software tell that the interference are not applicable then when I continue I can't see the full geometry only one solid part. You can read below what I got in the dialogue windows : Is it possible to know what could be the problem in this geometry?

Thanks

the error means that there is some topological issue and the import stops, so usually there are missing parts and you will never see the void fill.

Mostly it can be sorted out with this:

I've tried a little but it seems in your case the issue is not related to tolerances but rather to the modelling itself. Try to suppress some parts or cut the whole model into pieces to locate it...
