Hi, I need an advice on what i can do. I need to create an open inner region on this geometry i got an error. I there anything I can do to solve it on SimScale or I need to use 3D software ?
Hi there, thank you for using the forum!
Is this for an incompressible analysis?
It would probably be for two analysis : an incompressible one and, with the same model (with some modification), a conjugate heat heat transfer.
This is a complicated model with many small faces, so it will be hard to mesh and simulate unless you perform a lot of cleanup. Everything that is considered unnecessary should be removed, and small faces should be merged with their neighboring surfaces.
I would suggest to remove all faces except from the internal region like this, and solidify them to create the domain:
With your current model this is hard to achieve, as there are inconsistencies between the faces.
All in all, you should use a watertight geometry in order to extract the flow region, with a solid, merged enclosure, or delete all the other parts’ faces in your CAD software, and make a solid part so you can use this as domain.

All right, thank you for your answer !
