Default CFX4.3 -build analysis form

I am having problem creating a geometry because the CFX crashes whenever I perform the analysis. I am not sure if its the memory problem. I wonder if anyone has encounter this problem before. If yes, please let me know how I can solve the problem. I am doing a 3-D simulation that has 300000 elements. Thank you.

Can you offer the tips of this problem? maybe it is due to your poor 3-D geometry structures, such as you have some very thin surfaces or samll angles in them.

I have a fairly complicated geometry with 11 constraints. It is impossible for me to create the geometry without using the constraint.

The problem that I am facing is whenever I click apply on the Analysis form in CFX4.3, CFX crashes halfway through the analysis. It didn't give me any error message. It just crashes and I have to remesh the geometry and redo the analysis. I'm just wondering if this is a memory problem because I managed to create a .geo file when I mesh the geometry with less elements.

Are you using simple constraints or advanced constrains? You must avoid advanced constrains using multiblock structure.

Why not try andvanced constrain?
