sfepy/sfepy — Issue #160: Primer review request

The analytic solution in the primer example of tensile test of asphalt, is not seems to be an actual analytic solution, as it depends on the nodal forces. So the result of the solution varies with mesh refinement. For the same geometry and material property, analytic solution will not differ, even for extensive mesh refinement. it will always be the same. the analytic solution is derived from solid mechanics and there's no function of mesh or element. for that specific example, Analytic solution would be based on solid mechanics knowledge, getting the vertical and horizontal stress at the center of the disk due to application of 1mm displacement at the top.

Check, please, http://docs.sfepy.org/doc-devel/primer.html and (if ok) close the issue.

The primer has been fixed to use concentrated point load term, and truly the analytical solution, please verify.

Fixed now.
