Stress in Sensitivity-Based Shape Optimization

The ${\sigma }_{\text{vMises}}$ is the elemental centroidal von Mises stress summed up over the elements in DRESP definition using the P-mean Norm with a p-factor of 3. This is a differentiable approximation to the maximum von Mises stress and, therefore, GROUP_OPER = MAX must be used. Other GROUP_OPER settings are not allowed.
