CST2013: Frequency Domain Solver Parameters - Resonant: S-Parameter, fields

Simulation: Solver Start Simulation Frequency Domain Solver

If you are not familiar with the Resonant solver (application area, etc.), you should first read the Solver Overview or the Frequency Domain Solver Overview - Resonant: S-Parameter, fields. In this dialog, the optimization runs and parameter sweeps for your structure can be set up.

Solver settings frame

Accuracy: Defines the desired accuracy for the solution in terms of the relative error of the eigenvalues between Fmin and Fmax. This is the major break-off criterion for the solver.

Store result data in cache: Check here if you want the solver results to be stored in the result data cache. The efficient usage of the result data cache is explained in the printed documentation "Advanced Topics."

Calculate modes only: Enable this check box to calculate the port modes at the Eval. Freq. only (see below).

Resonant solver settings

Evaluation frequency: Specifies the frequency that is used for the waveguide port mode calculation. The factor must be set between Fmin and Fmax from the current frequency range.

Number of evaluation samples: You may specify the number of samples that will represent the S-Parameters. Please note that the simulation must be repeated if you change this number. Additionally, this number has virtually no effect on the total simulation time.

S-parameter settings frame

Norm to fixed impedance: S-parameters are always normed to a reference impedance. You may either select to norm them to the calculated impedance of the stimulation port or you may specify a number of your choice.

Adaptive mesh refinement frame

Adaptive mesh refinement: Mark this check box to activate the adaptive mesh refinement. The mesh will be adaptively optimized by successively changing the settings of the mesh expert system. Press the Properties... button to edit the current settings for the mesh refinement.

Start solver

Calculates the port modes and starts the frequency domain calculation.

Optimize...

This button opens a dialog box that allows you to set up and start an optimization run.

Par. sweep...

Opens the parameter sweep dialog.

Acceleration...

Opens the acceleration dialog box to control the high performance options of the simulation run (e.g. GPU acceleration, Distributed Computing, MPI).

Simplify Model...

Opens the simplify model dialog.

Apply

Store the specified settings without starting the calculation.

Close

Closes this dialog box without performing any further action.
