Pressure BC for solidDisplacementFoam
 

Hi,

I would like to use a pressure as a boundary condition with SolidDisplacementFoam and I am therefore looking for information about the tractionDisplacement type:

type tractionDisplacement;
traction uniform ( 0 0 0 );
pressure uniform 0;
value uniform (0 0 0);

- can the pressure at the surface be directly set in the "pressure" entry without specifiying anything else in the other entries?
- what does the entry "value" correspond to? Is it related to the entry "pressure" or the entry "traction"?
- is there another type more appropriate to set a pressure instead of a traction?

Thanks in advance
