Sensitivity-based bead optimization (BEAD_SENSITIVITY) makes it possible
to define very complex optimization tasks. It has been shown in industrial
size examples that the method is very powerful and attractive, especially
for dynamic problems.
The typical problems which can be solved by this algorithm are:
- Maximize stiffness (linear static)
- Minimize displacement for critical nodes (linear static)
- Maximize first eigenvalue (modal)
- Maximize a certain eigenvalue (using mode tracking)
- Move eigenvalues away from certain frequency (band gap optimization
with modal analysis)
