linear stress simulation problems
hello, I'm studying a support element (midplane section below). On the left, a vertical load is applied and the two red elements are radial supports.

Herebelow a view of half-model (symmetric with respect to the XY plane below).

Calculation performed on standard fem software show smooth stress concentration in the throat section.

With simsolid:
1 - first problem: the hemi-cylindrical surface is imported as a single surfaces (even if it is separated in order to apply the support restraints).
<?xml version="1.0" encoding="UTF-8"?>
2 - stress distribution is unrealistic, even worse if I set forther refinements (activate feature adaptation or increase the number of adaptive solutions). Here is the von Mises stress with default options

Any idea? here annexed the model (test.zip).
