Hydrostatic pressure with shell elements

Bug Reports
1

Hi,

it seems that hydrostatic pressure works fine with solid elements but there is some issue with shells. The results are x times higher than they should be (according to Abaqus and analytical calculations) where x is the thickness assigned to the shell section. I assume that it’s because the calculation of the hydrostatic pressure doesn’t take the shell thickness into account (as was mentioned in the thread about the development of this feature).

Here’s an example (the thickness was 10 and results are approximately 10 times higher than expected):

ppm

abq
abq1258×766 46.8 KB

ppm2
ppm21372×726 44.2 KB

abq2
abq21257×758 41.2 KB

@Matej Would it be possible to fix this? If not, can you suggest some workarounds? Maybe for now, PrePoMax could just multiply all the results from each shell element by its thickness?

I will fix this immediately since this should not happen. I did some comparison evaluations for solids but for shells, I only checked one model using the thickness of 1. So I probably missed it.
