IESolver Object

This object together with the FDSolver Object controls the integral equation solver and multilayer solver.

 

Integral Equation Solver Settings

Integral Equation Solver General

Reset

Resets all previously made settings concerning the solver to the default values.

 

UseFastFrequencySweep  ( bool flag )

Activates (flag = True) or deactivates (flag = False) the broadband frequency sweep for the solver.

 

UseIEGroundPlane  ( bool flag )

Activates (flag = True) or deactivates (flag = False) the infinite ground plane formulation for an electric boundary condition at ZMin.

 

PreconditionerType  ( enum{"Auto", "Type 1", "Type 2","Type 3"} key )

Sets the preconditioner type.

 

LowFrequencyStabilization  ( bool flag )

This option controls the low frequency stabilization for the iterative and direct MoM solver. If enabled the accuracy for electrically small models or models with small triangles compared to the wavelength will increase.

 

LowFrequencyStabilizationML  ( bool flag )

This Multilayer solver option controls the low frequency stabilization for the iterative and direct MoM solver. If enabled the accuracy for electrically small models or models with small triangles compared to the wavelength will increase.

 

Multilayer  ( bool flag )

Activates (flag = True) or deactivates (flag = False) the multilayer solver.

 

SetiMoMACC_I ( double value )

This accuracy determines the accuracy of the Iterative MoM system matrix for the Integral equation solver. A lower accuracy leads to lower memory requirement but also to a lower accuracy.

 

SetiMoMACC_M ( double value )

This accuracy determines the accuracy of the Iterative MoM system matrix for the Multilayer solver. A lower accuracy leads to lower memory requirement but also to a lower accuracy.

 

SetCFIEAlpha ( double value )

If the option UseCFIEForCPECIntEq is enabled and the CFIE alpha is set to 1 the Electric Field Integral Equation will be used. This is an option if you are sure there will be no spurious resonances inside the PEC solids e.g. for electrically small PEC solids. The default value is 0.5.

 

DeembedExternalPorts ( bool flag )

Activates the automatic deembedding of external ports as multipin ports.

 

IgnoreBC_XY_And_Set_To_Open ( bool flag )

This command is used to control the handling of boundary conditions in x- and y-direction for the Multilayer Solver.  If flag is set to "True" the boundary conditions in x- and y-directions will be set to open. If flag is set to "False" the boundary conditions in x- and y-directions will be set as defined with the methods of the Boundary Object.
