[sfepy] Displacement interpolation at arbitrary point

Hi Robert,

I was looking for a postprocessing method to calculate the displacements for points on the surface of the mesh that are not necessarily node points. Precisely I need a interpolation function that gives me the displacement of these points. The input would be the already calculated linear elastic problem from my earlier example with the node displacements as result.

In the sfepy documentation I found the probing described here: http://sfepy.org/doc-devel/primer.html#sec-primer

Is this the right way to solve the interpolation? Do you recommend something different?

Thank you and regards, Kathrin
