General

Multilevel Meshing This option generates the mesh automatically in several steps, and it is usually more efficient (in terms of runtime) than common mesh generation, so it is selected by default. However, minor differences may appear between the meshes obtained with and without multilevel mode.

Use Multilevel Meshing enable this option to use the multilevel mode.
First frequency The frequency of the first step may be specified by the user with this parameter. If this field is empty, the first frequency is automatically computed. It is only considered when the Multilevel Meshing is enabled.

Memory Factor This option allows a reduction of the memory resources required in the mesh generation process. The memory allocation is an automatic feature in this process, so the highest one is selected by default to ensure that the mesh will be successfully obtained. If the memory resources exceed the available memory, the message "ERROR Not enough memory. Please, try decreasing Memory Factor" will appear to suggest decreasing this factor. Sometimes, a short factor may lead in not enough allocation for the required mesh resolution.

Volumetric Meshing When a dielectric material is assigned to any geometric object, it may be defined as a volume, so it will be meshed with hexaedrons instead of quads. If there are any volume in the geometry, this section is enabled.

Mode This option allows to change the algorithm used in the mesh generation process of dielectric objects (defined as Volumes). Two different modes are available:
- Structured Mesh All elements of the volumetric mesh are perfect parallelepipeds. This method is an approximation of the real shape of the dielectric objects by simple cubes. Some parts of the mesh can be out of the volume and other regions can have incomplete regions, but the average volume of the mesh is very similar to the volume of the original dielectric objects. This algorithm is the fastest one.
- Conformed Mesh Most of elements of the volumetric mesh are perfect parallelepipeds, but only in the completely inner regions of them. The inner structured mesh is joined with the boundaries of the volume by using hexahedrons of variable shapes. This method is more accurate than the Structured Mesh, but is also slower and irregular elements may appear in specific cases.
Divisions Different divisions per wavelength for the X, Y and Z dimensions may be considered for meshing the volumetric objects. If some of this field is empty, the divisions specified in the main Meshing Parameters window are assigned.

Topology If the electrical continuity between the surfaces have to be broken, the option Disable topology must be selected. Note that the accuracy may be reduced when the electrical continuities are not correctly analyzed as virtual fissures are introduced.

Edge Refinement Within this section, the border effect in the mesh generation may be configured. The border effect consist on generating thinner elements in the boundary of the surfaces than the meshing size, so currents analysis is more accurate. This function is recommended for analyzing planar structures.

Edge Refinement This option allows enabling the modelling of border effect in the mesh generation.
Edge Factor It represents the portion of size of the final elements to model the border effect the higher is this value the are the boundary elements. This parameter may be higher than 3. It is only enabled when Edge Refinement is selected.
