Global PropertiesSpecialsRefinementRefine at PEC / lossy metal edges by factor
This option increases the spatial sampling at PEC or lossy metal edges. At these edges additional density points are added that force the automatic mesh generator to increase the mesh density at those points by the given factor.
This setting is very useful because at metal edges, singularities occur in the electromagnetic fields. This means that the fields vary significantly near such edges and must be sampled more frequently than elsewhere.
The behavior of the generator is slightly different if the fixpoints are located on a straight or an elliptical line. For straight lines, the mesh lines of the two perpendicular coordinate directions are influenced. For elliptical lines, this is the case only for the normal direction of the area that is defined by the edge.
Consider PEC / lossy metal edges along coordinate axes only
Use this option to reduce the mesh refinement along a curved structure.
Mesh refinement inside dielectric / permeable materials
None: No mesh material based mesh refinement
Wavelength refinement:
Dielectric and permeable materials influence the wavelength of the electromagnetic
fields. With this setting, the mesh density for the affected structures
will be adjusted according to this effect.
This option is available in CST EM STUDIO only for compatibility reasons
with CST MICROWAVE STUDIO.
Low frequency refinement: The mesh density is set depending on the material parameters. Higher permittivity or permeability leads to moderately finer meshes.
