I&#8217;ve seen some posts here in the forum, but for some reason I am not being able to properly reproduce it myself.<\/p>\n<p>The problem is a standard Hertzian Contact between a sphere and a plane in which I want to evaluate identation, stresses and contact radius to compare to the analytical solution. I am simplifying it to a 2D problem with symmetry.
