Mesh commands
*REFINE
entype, enid, level, gid, thick, $d_{min}$, $\alpha_{max}$, deactivate
entype, enid, level, gid, thick, $d_{min}$, $\alpha_{max}$, deactivate
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.
