*min_size_node_movement
Move feature nodes to solve minimum element size failures.
Syntax
*min_size_node_movement mark_id
Type
HyperMesh Tcl Modify Command
Description
- Move across shared edges
- Move across free edges
- Move across non-manifold edges
- A set of 1D elements along FE edges
- If no 1D element is present in the model, using the feature angle given in the paramter file
- Node - geometry association
Node - geometry association is maintained after feature node are moved, however, free edge nodes may move tangential away from the surface and lose association.
- Internal low curvature shared edges
- Internal high curvature edges
- Free edges
- Non-manifold edges
Node movement is also part of the *rebuild_mesh command.
Inputs
- mark_id
- The ID of the mark containing the elements to correct. Valid values are 1 and 2.
Example
To move feature nodes of selected shell elements with 5 mm criteria and parameter file settings:
