The above picture is the simulation in question. I have applied 100Mpa of pressure to the cavity surface.
My first question is why are the arrows so speratic? there are no arrows showing pressure in the corrner even though I do have pressure applied there... Do the arrows really mean anything at all?
The more pressing matter is the stress ammounts. From what I understand I should be seeing an equarilibrium on the surface where the pressure is being applied. That means I should see -100Mpa across the whole thing or blue in the picture. Why do the corners show above -70Mpa? Is the program for some reason only applying pressure to the flat surfaces that could explain the odd numbers.
