Description

Attempts to mesh two disconnected element/component sets within a certain proximity with each other.

Inputs

source_entity_type

The type of entity to use as source. Valid values are comps and elems.

source_mark_id

The ID of the mark of source entities. Valid values are 1 and 2.

target_entity_type

The type of entity to use as target. Valid values are comps and elems.

target_mark_id

The ID of the mark of target entities. Valid values are 1 and 2.

proximity

The value within which the source and target elements should be fused. Value must not be negative.

options

List of input options, passed as a space separated string enclosed in quotes. Valid options are:

BridgeGaps=<value>: 0 - Stitches the source and target by imprinting source on target (default); 1 - Creates bridge elements between source and target instead of stitching , thereby retaining the source curvature
BridgeGapTol=<value>: The value beyond which the source nodes found under proximity with target will be bridged. Only valid when BridgeGaps is enabled. Default value is the global node tolerance.
ClusterRemovalMaxWidth=<value>: During mesh fusing, some isolated clusters on source can remain. This defines the mesh maximum width within which if clusters of elements formed after fusing, they are removed. Value must not be negative. Default value is 0.0.
DoRemesh=<value>: 0 - Do not remesh fused elements (default); 1 - Remesh fused elements
FeatureAngle=<value>: The value to define features in the range of 0 to 180. Default/common value is 30.0.
FuseFreeEdgesOnly=<value>: 0 - Fuse all elems within proximity (default); 1 - Fuse only free edges within proximity
NodeFeatureSnapTol=<value>: The value within which the nodes positions resulting after the fusing of source and target elements can be snapped to features. Value must not be negative. Default value is 0.0.
ProjectionType=<value>: 1 - Projection and further stitching happens along shortest projection direction of source nodes to the target (default); 2 - Projection and further stitching happens along the tangential projection direction of source nodes to the target; 3 - Projection and further stitching is attempted along the tangential projection direction of source nodes to the target, however if the tangential projection fails , shortest projection is considered
RemoveTargetTails=<value>: 0 - Do not remove target tails (default); 1 - Remote target tails with tolerance provided in RemoveTargetTailTolerance option; 2 - Remote target tails with internaly calculated tolerance
RemoveTargetTailTolerance=<value>: If the width of the tail of the target tail face lies within this value, it is removed. Valid only when RemoveTargetTails is enabled. Default value is 0.0.
RemoveSharedTargetFace=<value>: 0 - Do not delete faces shared by source and target at all edges formed at the target after fusing (default); 1 - Delete faces shared by source and target at all edges formed at the target after fusing (default)

Examples

To fuse components 100 and 200 within a proximity of 40, with various fuse options:

*createmark components 1 100
*createmark components 2 200
*fuse_shell_mesh components 1 components 2 40 "ClusterRemovalMaxWidth=30.0 DoRemesh=1 FuseFreeEdgesOnly=1 BridgeGaps=1 BridgeGapTol=0.0 ProjectionType=3 RemoveTargetTails=1"

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
