Adaptive Setup for Non-Transient Solutions
To specify adaptive settings, click the General tab in the Solve Setup dialog box and use the options in the Adaptive Setup section. Adaptive settings include the following:
- Maximum Number of Passes:Defines the maximum number of mesh
refinement cycles you would like Maxwell to perform. This
value is a stopping criterion for the adaptive solution; if the maximum
number of passes has been completed, the adaptive analysis stops. If
the maximum number of passes has not been completed, the adaptive analysis
continues unless the convergence criteria are reached.
Note: The size of the finite element mesh — and the amount of memory required to generate a solution — increases with each adaptive refinement of the mesh. Setting the maximum number of passes too high can result in Maxwell requesting more memory than is available or taking excessive time to compute solutions.
- Percent Error: Controls the desired solution accuracy. Smaller values produce more accurate (but slower) solutions; larger values produce less accurate (but faster) solutions. At each step in the adaptive process, the energy and error energy are computed, and you can view the most recent solutions as soon as they are completed. After the mesh is refined, the matrix is calculated on the refined mesh. The relative change between the previous matrix and the current matrix is then computed and reported as the matrix delta; the target matrix delta is the Percent Error. A small delta indicates that further mesh refinement will probably not change the solution.
