how to load pressure on the solid element?

extract the faces of the element and apply suitably on the required surface

In that case, what would be the property to assign to that surface? PSHELL? And thickness? I have checked that thickness influences results in this case.
Thank you in advance,

Hi
Just apply a very thin thickness, bending will be neglectable
But it is faster and simpler to apply pressure directly to solid elems

Hi,
¿And how can I apply these pressures directly to solids when I want to apply a field? As long as I know, if I choose a few solids elements from field selector, pressure is applied on the middle of the elements instead of on the external surface.
Thank you once again,
Pablo.

Now from version 14.0 you can apply pressure by faces (no need to extract faces) & pressure acts on element normal direction.

What I want to do in the end is applying a pressure (import from an ansys model) which is initially applied beneath a thin layer of 2D elements, created automatically when imported. But I have checked that, even it seems to be correctly configured, when I modify 2D elements properties, results (displacement plot) also change, a lot. F
I have used as 2D elements properties:
- PSHELL
- T=0.001 mm
- Material settings similar to steel and other property settings by default.
General appereance of results, when compared to the ansys one (which is checked), is very different so I suspect that this way of applying pressure is the main cause of the discordance. I would appreciate any kind of advice or suggestion.

Yes this method applying pressure is not good I think. You should apply pressure directly on solid elems. If you cannot do it your self, send us your model, we could give a try

I have been able to solve this problem introducing a very thin thickness as you said, and results are good enough. Finally the problem were material properties which depended on temperature. Thanks for the offer.
