Hi,

I am trying to fill and then maintain a chamber with constant pressure, then look at the deformation of one side. Similar to a balloon. But I want to know how do I cause the deformation using a constant pressure.

I tried a stationary Fluid Solid interaction, but I can't seem to get it to deform.

I also just used a face load in Structural Mechanics, but I basically received a balloon being pushed in the center, instead of pressure pushing in all directions.

A face load in a structural analysis should work. Make sure you apply it as a pressure and activate geometric nonlinearity. That way the direction of the pressure load (and the magnitude of the total force) will be updated with deformation.
