4.4     Mesh Refinement

QuickWave enables some mesh refinement mechanisms. Among them the automatic meshing (AMIGO) and mesh snapping planes can be mentioned. The main mesh refinement mechanism is the one that allows changing the FDTD mesh locally, namely dense the mesh or make it coarser. There are two options allowing for that depending on the Input Interface:

• In QW-Editor we have mesh special planes that allow enforcing a specified cell size above, below, and above and below the position that they are placed at. The new mesh setting is forced to the border of scenario or to the next mesh special plane (so allows for mesh modifications also in the limited area inside the scenario, by using “above” and “below” special planes). The mesh special planes are available along all three directions. This option allows for both, locally decreasing and increasing the cells size comparing to the maximum cell size calculated for the project in a given direction.

 Attention: When using the mesh special planes together with AMIGO option, the smallest cell size enforced by either of those options in a given area is always set by the software. If the reinforcements of different mesh special planes overlap, the smallest cell size is set in the joint area.

• In QW-Modeller and QW-AddIn for Autodesk Inventor Software the mesh refinement is enabled with Mesh Box option. Mesh Box is a simple object, which enables setting a specific meshing in the area limited by its size. Mesh Box allows enforcing a specified cell size in a chosen direction, assuming that it is not bigger than the maximum cell size calculated by the software along this axis.

Attention: When using the Mesh Box together with AMIGO option, the smallest cell size enforced by either of those options in a given area is always set by the software. If different Mesh Boxes overlap, the mesh cell size in the overlapping area is determined by the Mesh Box with the smallest cell size.
