4. B modeling: geometric method

4.1. Characteristics of modeling

An auxiliary grid is not used. We’re going to test option TORE. The radius of the cylinder (\(4\mathrm{mm}\)) coincides with that of the torus.

4.2. Characteristics of the mesh

The same mesh as that of modeling A. is used.

4.3. Tested sizes and results

We test that the maximum and minimum values of the difference field are equal to zero.

Option TORE therefore correctly calculates the group of nodes that belong to the torus of given radius built around the bottom of the crack.
