Some models can only be analysed using on-demand FEA

For some models, only on-demand FEA is available

For some models, with more complex geometry, only the Online FEA method is available. For example, the user-defined axial mode sonotrode has its geometry defined by 13 diameters and 12 section length dimensions. With so many possible inputs the range of geometry is enormous and constructing a database of results is not practical.
