Mr. Peter;

The frictionless support was applied bottom of the model to restrict the vertical movements. It is not on the surface that applied nodal displacements. 

3D model is Earth structure, vertical surfaces are tectonic faults and the nodal displacements are GPS velocities.  The velocities (per year values, so I use them as displacement) were determined relative to the northern part of the model from long-term GPS coordinates. I've tried to find the stress (per year) value on the fault lines.
