Advanced Solver Properties
This section provides detailed explanations of some of the properties that control the behavior of the SNOPT optimization solver in the Optimization Module.
When solving multiphysics optimization problems in the COMSOL Desktop using the Optimization interface, some of the properties listed in this section can be controlled while others always take their default values. Modifying the value of those properties requires that the value is changed using LiveLink™ for MATLAB® or by running a compiled COMSOL API history file.
In the following sections, ε represents the machine precision (available as eps in MATLAB) and is approximately equal to 2.2·10−16.
