Hi, everyone.

I had problem when I was revolving the 2D object. As I going to boundary mode in 3D from Draw mode, i facing with this error "Error 2100, Internal error in geometry decomposition."

Thanks in advance.

Hi

often it comes from the interaction of volumes when revolving, normally you should avoid revolving over itself. But it might be something else too ;) Perhaps linked to the geometry resolution ?

Good luck

thank you for your suggestions.

what do you mean "you should avoid revolving over itself" ?

And whats your idea about this error ," Error 2023, Could not resolve subdomain relations."

Thanks for whole your help.

Hi

when you revolve i.e. with a twist (might not be possible back in 3.5) you can get the resulting volume to interact after 1 turn, such small overlaps gives often problems for the geometry analyse operation. But as I said, you might have another issue. most COMSOl error message are/were quite cryptic. It's getting better in v4 ;)

Hi


I did not have this overlaps that you said.
I try to do simulation with v4.

Thank you so much.
