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.
This option applies the predefined factorisation type adopted by the Solver.
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).
