Boundary layer |
Menu: Mesh->Boundary layer
A boundary layer mesh is one mesh attached to the boundary, and which has a certain distribution of nodes separated from the boundray following a certain stretching function. The streching function and the grow factor of the boundary layer meshes of a model can be set in Preferences->Meshing .
User can define two main properties to the boundary layer meshes of each geometrical entity: First layer height and Number of layers. When selecting the entities which will have boundary layer mesh a window shows a schematic picture, where user can see the distribution of heights of each layer, and the total height of the boundary layer mesh when the assigned properties are set.
