MMA Solver Properties
In addition to the settings available in the COMSOL Desktop, MMA when called through the API allows explicit tuning of the approximating subproblems solved in each inner iteration. In particular, update rules for the moving asymptotes can be modified. It is also possible to switch off the automatic transformation performed on least-squares, minimax and maximin problems, as well as disable the globally convergent extension of the MMA method.
