Error limit

If the relative deviation of the energy between two passes is smaller than the error limit the mesh adaptation will terminate.

Minimum number of passes

This is the minimum number of passes which will be performed, even if the results does not change significantly. Sometimes the adaptive mesh refinement needs a couple of passes to figure out the location of the most important regions. Thus it rarely may happen that the results do not change during a few passes but afterwards change in order to converge to the final solution.

Maximum number of passes

This setting determines the maximum number of passes to be performed for the mesh adaptation, even if the results have not sufficiently converged so far. This setting is useful to limit the total calculation time to reasonable amounts.

Refinement strategy

Determine here the strategy used for the adaptive mesh refinement. Two different possibilities are available, either based on the modification of the mesh expert system or determined by regions of field energy in the calculation domain.

Expert system based

Choosing this strategy the mesh refinement is performed by successively changing the settings of the mesh expert system. This offers the possibility to run the mesh adaptation only once in order to generate an appropriate mesh line distribution for the current simulation model. This optimized mesh can be used afterwards for further calculation runs with modified parameters (e.g. parameter sweeps or optimization cycles) without activating the refinement process again.

Mesh increment: This parameter determines the changing of the mesh expert system by increasing the settings of the lower mesh limit in the Mesh Properties dialog box.

Energy based

Choosing this strategy the mesh refinement is based on the given energy distribution of the electromagnetic fields inside the calculation domain.

Factor for mesh cell increase

This factor determines how many new cells are introduced between two subsequent passes of the mesh refinement. A setting of 0.5 means that 0.5 times more mesh cells are used for the next calculation than have been used for the previous one. In other words: the number of mesh cells increases about 50 percent from pass to pass.

Refine in X/Y/Z direction

If a button is checked, the mesh will be refined along the corresponding coordinate direction. This option is useful to avoid refining a mesh along coordinate directions in which the structure’s fields have no dependency (e.g. some quasi-2D structures).

Losses based

Choosing this strategy the mesh refinement is based on the given loss distribution of the electromagnetic fields inside the calculation domain.

Factor for mesh cell increase

This factor determines how many new cells are introduced between two subsequent passes of the mesh refinement. A setting of 0.5 means that 0.5 times more mesh cells are used for the next calculation than have been used for the previous one. In other words: the number of mesh cells increases about 50 percent from pass to pass.

Refine in X/Y/Z direction
