I'm trying to make FloXpress in my imported rhinoceros file (exported as parasolid) [image1]. I can visualise it sectioned [image2] but when I accept the action it is seen like this [image 3]. So that, when I start the Floxpress simulation I get geometry comprobation message [image 4]. It's obvious that the problem is with the formalisation of the solid in rhinoceros but I dont know how to make it properly.

Can someone advise me on how to do it? I attach both files in order you to prove if you want it!

Thank you so much guys
