entype, enid, level, gid, thick, $d_{min}$, $\alpha_{max}$

Parameter definition

VariableDescription
entype Entity type
options: P, PS
enid Entity identification number
level Level of refinement
gid ID of a GEOMETRY that defines a sub-space for refinement
default: all elements in the selected part/part set will be refined
thick Optional special refinement level in through thickness direction. The option only works for structures that are modeled with one element in thickness direction.
default: same as level
$d_{min}$ Minimum element dimension for refinement
default: all elements are refined
$\alpha_{max}$ External element face smoothing angle
default: no surface smoothing

Description

This command is used to refine the grid in a selected region of a part or part set. Pentahedra and tetrahedra elements can currently only handle refinement level = 2. 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_off option.
