Model and execution

What was calculated?

The model uses 1,063 quadratic tetrahedra and 1,992 nodes.
The circular shaft has the same geometry, connectivity, coordinates, restraints and loads in both solvers.
The figure shows CalculiX deformation for the torsion model.

How to read the evidence

What the results say

The relative difference is 6.84 × 10⁻⁵ for the full displacement field and 6.45 × 10⁻⁵ for terminal twist.
