hm_checkproximity
Checks proximity between elements/components.
Syntax
hm_checkproximity entity_type mark_id max_proximity ?mode? ?check_side? ?proximity_scheme? ?proximity_by_edge? ?min_angle_limit? ?max_angle_limit?
Type
HyperMesh Tcl Query Command
Description
Checks proximity between input entities and returns list of entities within the specified proximity. The output depends on the mode argument as defined below.
Inputs
- entity_type
- The type of entity to check. Valid values are elems and comps (only elems in comps are considered).
- mark_id
- The ID of the mark containing the entities to check. Valid values are 1 and 2.
- max_proximity
-
The maximum distance beyond which an entity is not considered.
- mode
- 1 - Global proximity (default)
- check_side
- 1 - Check both sides of elements
- proximity_scheme
- 0 - Checks basic proximity along a ray from the element center along the normal direction.
- proximity_by_edge
- 0 - Ignores proximity for nearby edges (default behaviour if not specified).
- min_angle_limit
- If the angle between the proximate element pairs is less than this value, such pairs are not reported.
- max_angle_limit
- If the angle between the proximate element pairs is greater than this value, such pairs are not reported.
Example
To find proximity between all components using a max distance of 2.5:
*createmark comps 1 all
hm_checkproximity comps 1 2.5
