Please, I need help on how to implement topography optimization and bead optimization to improve structural stiffness of engineering component in Comsol. Thank you.
I am linking Comsol with Matlab. I can compute the strain energy density on the nodes of the finite element (Ws) and the unit is J/m^3. But I need the strain energy on each element of the finite...
