Can someone help me to check out my geometry? thank you!

Hi,
I created my geometry, and when I try to set up the subdomain conditions, I can choose any domain?

I draw the geometry using curves, it is a single vein valve, do I need to union the curves to make a rectangle or other shape, make sure it is enclosed?

Thank you so much!

Hi

you main issue is that you have only lines and no areas in 2D such that you end up with only boundaries but no domains. You need to perform a "Convert to solid" (remove your two unions and perform this on all items at the end just before the finish) and then you might "split" all if you need to manipulate further individual items in the geometry process

Turn on your "Selection List" (side by side with the model Builder) and check that you have domains, boundaries and points by selecting the different graphical icons top right of the graphics screen

Good luck
