─ 2.2. Solver Parameters
The recommended values for the solver configuration are explained in this section.
This example may be solved with the default parameters. The most important parameters within the Solver – Parameters panel are listed:
Solver Method: The Method of Moments (MoM) is a full wave analysis method and will be considered for this benchmark. Physical Optics (PO) is faster and requires less memory, but should only be used in those cases involving large and smooth objects, due to its asymptotic nature.
Architecture Strategy: Both MPI and OpenMP provide similar results whenever the machine supports them. OpenMP is not compatible with distributed memory systems, although it can be more efficient for shared memory systems such as workstations.
Electromagnetic Equation: the only option that can be applied in the present case is EFIE because MFIE and CFIE require a closed conducting volume with its normal vectors pointing outwards.
Solver Functions - Advanced Options: Use this window to modify any advanced configuration of the Solver. For analyzing problems similar to the considered one, the Preconditioner may be used to notably improve the convergence of the iterative process and reduce the simulation time.
Other Parameters: The Relative error may be reduced to ensure a higher accuracy in the resolution of the problem. At most an error of 0.01 (or even smaller) is especially recommended when the SAI preconditioner is selected.
The configuration shown in the next figures has been used to analyze this benchmark.
