Advanced Solver Settings
Advanced solver settings are available to reduce the memory footprint or speed up a solution for specific types of models.
On the Solve/Run tab, in the
Solution Settings group, click the 
Solver Settings icon. On the Solver settings dialog, click the
Advanced tab.
Factorisation for Parallel Execution
This option allows you to select between using standard full-rank factorisation or
block low-rank (BLR) factorisation when using the parallel solver. Changing the
factorisation method can reduce the memory footprint of the sparse LU-based
preconditioners in some models where the solution methods are MLFMM or FEM.
- Default
- This option applies the predefined factorisation type adopted by the Solver.
- Auto
- This option applies automatically the optimum factorisation type based on the model.
- Use standard full-rank factorisation
- This option applies the standard full-rank factorisation.
- Use block low-rank (BLR) factorisation
- This option applies the block low-rank (BLR) factorisation.
Tip: In most cases default gives the best
performance.
Compression for Looped Plane Wave Sources
This option is an accelerated method that can be used to speed up the solution for a model that contains a plane wave source that loops over multiple directions (for example, when calculating RCS).
