Hello,

I am trying to run a stress analysis case using openFOAM 1.4, and the solidDisplacementFoam solver.

Firstly... is the solver capable of being used for relatively complicated 3D cases, with multiple constraints? Or is it only a demo solver, primarily for 2D applications?

I was looking at the different boundary conditions in the tutorials, but was not able to find all the boundary conditions I need.

1. How can I constrain motion of a patch to only one degree of freedom? For example... fixed in the x and y directions, but movable in the z direction?

2. In the tractionDisplacement condition, what do the "traction", "pressure" and "value" terms imply? And what units do they take?

3. What does the "slip" boundary condition do? Can that be used to selectively constrain different directions?

Awaiting a reply.

Have a nice day!
