Parameter definition
Variable | Description |
---|---|
entype | Entity type |
enid | Entity identification number |
level | Level of refinement |
gid | ID of a GEOMETRY that defines a sub-space for refinement |
thick | Optional special refinement level in through thickness direction. The option only works for structures that are modeled with one element in thickness direction. |
$d_{min}$ | Minimum element dimension for refinement |
$\alpha_{max}$ | External element face smoothing angle |
deactivate | Deactivated refine directions |
Description
This command is used to refine the grid in a selected region of a part or part set. Tetrahedra elements can currently only handle refinement level = 2. For pentahedra elements the in-plane refine level must be an even number.
The surface of the refined region is smoothed if the angle between two adjacent element faces is smaller than or equal to $\alpha_{\mathrm{max}}$.
Example
Mesh refinement
Local mesh refinement of a thin walled structure using the thick option.
