The 3D version of the load seems to work just fine. However, the 2D axis symmetric version does not seem to work as desired. It seems to be 10 times less pressure and not evenly distributed. I’m not an FEA expert by any means, but I think it is related to the way the pressure is integrated over the nodes. I saw a post about a 2D application where the stress was 10 times more than expected. Its possible that when that was fixed, it affected this one.

here is the uniform load in 3D. I applied 10MPa and 10MPa is shown.

here is the uniform load in 2D. I applied 10MPa and 10MPa is shown.

Here is the hydrostatic load. I applied 10MPa at two end points and direction from end point to end point:

the little fold is the center of the axis where one would expect there to be a more even distribution. And notice how it shows around 1MPa and not 10MPa as applied.
