Hello,

I am working in poromechanics. I need to give stress boundary condition. I am having some problem near the boundary but solver is working fine in inside the domain and away from the boundaries.

I want to want to ask what is the difference between solidTractionFree and tractionDisplacement with 0 pressure and 0 traction values. Please clarify.

Another thing, what is the difference between solidTraction and tractionDisplacement boundary condition?
