When the Create Mesh option is selected, the following panel will be shown on the right side of the window:

Divisions per wavelength: The user may specify different mesh density in planar and curved surfaces. Planar surfaces are contained in a single plane, otherwise surfaces are curved.
Processors: Use this to set the number of processors used for the meshing process.
- The Advanced Settings are explained below:
- General: there are some options to specify in this tab.
Meshing advanced parameters general tab
Multilevel Meshing. Enable this optionto generate the mesh automatically in several steps. This option 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. The frequency of the first step may be specified by the user in the First freq field, but when this field is empty, the first frequency is automatically computed.
- 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 depictedin the next Figure will appear to suggest decreasing this factor.
- Topology. If the thermal continuity between the surfaces have to be broken, the option Disable topology must be selected. Note that the accuracy may be reduced when the thermal continuities are not correctly analyzed because virtual fissures are introduced.
Surfaces Replication: there is only one option called Parameters in this tab that is composed by some sub-options.
Meshing advanced parameters surface replication tab
- By marking the Replicate Open Surfaces option, a parallel layer of open objects is generated in the mesh generation process. If replication is marked, the elements of all the open objects are replicated to an automatic frequency-dependent distance from the original ones. By clicking on the advanced button, the window shown in the next Figure will appear where additional features can be configured.
- Replication Area. The criterion to replicate open objects can be edited.
- Automatic Replication. Any object with a total area greater than:
- Replicate all open objects. Any object is replicated, by default.
- Replicate objects with area greater than. To specify manually the threshold of the minimum total area of the objects to be replicated, in square meters.
Replication Distance. The distance between the original objects and their parallel replicas can also be edited.
- Automatically calculate. By default, the distance is given by the following expression:
- Specified distance. To specify manually the desired distance, in meters.
Geometry: the followings parameters can be specified.
Meshing advanced parameters geometry tab
Study Geometry. To pre-process the input geometry, evaluating some features such as its sizes or electrical continuities.
- Study Edges. To delete the edges of the input surfaces that are shorter than the Minimum Edge parameter (in meters), extending its adjacent edges. This option is only enabled when the Study Geometry button is enabled.
- Study Loops. To delete the loops of the input surfaces that are shorter than the Minimum Loop parameter (in meters). This option is only enabled when the Study Geometry button is enabled.
- Study Areas. To delete the input surfaces that are smaller than the Minimum Area parameter (in square meters). This option is only enabled when the Study Geometry button is enabled.
- Detect Topology. To detect automatically electrical continuity between neighboring surfaces that are very close but have not been modeled with precise continuity. The maximum separation allowed to set the electrical continuity is the Maximum Distance parameter (in meters). This option is only enabled when the Study Geometry button is enabled.
- Split Curves. To divide the curved borders of the input surfaces that have a curvature greater than the Maximum Arc parameter (in degrees). This option is only enabled when the Study Geometry button is enabled.
- Scale Geometry. To scale internally the geometry during the meshing process. When the mesh generation finishes, the output mesh has the same sizes as the original geometry. This option is useful for meshing very small structures. This option is only enabled when the Study Geometry button is activated.
