The substrate is a rectangular prism, with a non-homogeneous surface, but the tip is exactly tangent for sure. The indenter already has a small radius at the tip. The Fixed Support is defined by experimental data, so that cannot be varied. I have created a Translational Joint, but still the message of invalid boundary conditions appears. In the next picture you can see the boundary conditions, being the force application in the z axis.
