*equivalence
Equivalences or finds duplicate nodes of selected components, elements or nodes within a tolerance.
Syntax
*equivalence entity_type mark_id tolerance mode location numbering ?equivalence_to_meshnodes?
Type
HyperMesh Tcl Modify Command
Description
Equivalences or finds duplicate nodes of selected components or elements within a tolerance.
Inputs
- entity_type
- The entity types to consider. Valid values are elems, comps and nodes.
- mark_id
- The ID of the mark containing the input entities. Valid values are 1 and 2.
- tolerance
- The tolerance used to find neighboring nodes to equivalence.
- mode
- Operating mode of the command:
- 0 - Preview found nodes.
- 1 - Equivalence found nodes.
- 3 - Place found nodes on user mark.
- location
- Location of equivalenced nodes:
- 0 - Equivalence at the location of the node with the lowest ID.
- 1 - Equivalence at the location of the node with the highest ID.
- 2 - Equivalence at the midpoint of the two nodes.
- numbering
- The numbering of the retained node:
- 0 - Retain the number of the node with the lowest ID.
- 1 - Retain the number of the node with the highest ID.
- equivalence_to_meshnodes
- Optional. The equivalencing to mesh nodes:
- 0 - Retain the behavior with the location and numbering argument (default).
- 1 - Ignore location and numbering argument. If one temporary node and a mesh node are to be equivalenced, always equivalence to mesh nodes and delete the temporary nodes, which are equivalenced.
Example
*createmark comps 1 displayed
*equivalence comps 1 0.1 1 0 0
*createmark nodes 1 1-100
*equivalence nodes 1 0.1 1 0 0
