SimulationXpress on a Dome Component.

Hi,

I am currently trying to do an analysis on a dome component. It is hollow with a .030" wall thickness. I was using 60 psi.

-Side not this dome acts as a water jacket to another dome

-It also is welded into a flange.

My simulation error is found from the fixtures end resulting in a mesh failure. However when I place a bottom on the dome the fixture works fine. That being said I am hesitant to trust the simulation due to having a bottom, the pressure no matter how high I raise it sees to stay the same which I know is incorrect.

Is there a better way to fix the mesh?
