Browsers provide a structured view of model data, which you can use to review, modify, create, and manage
the contents of a model. In addition to visualization, browsers offer features like search, filtering, and sorting,
which enhance your ability to navigate and interact with the model data.
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry
is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing
parts. The current capabilities are focused on stiffening parts.
Use PhysicsAI to build fast predictive models from CAE data. PhysicsAI can be trained on data with any physics or
remeshing and without design variables.
Explore, organize and manage your personal data, collaborate in teams, and connect to other data sources, such as
corporate PLM systems to access CAD data or publish simulation data.
This realization uses the prop_cweld.tcl property script.
CWELD Realization Options
Option
Action
use shortest
projection for center / use connector position for center
use shortest projection for center
From the connector position the closest node (shell
or solid) is identified. This node becomes the GS
node.
If a node is defined as link, this option will be
ignored and use connector position for center is
selected instead.
use connector position for center
The connector position is used for the later GS
node.
If the connector has a node link defined, this node
becomes the GS node. This can be used to create a
CWELD attached to a SPC node.
If the connector is very close to an existing node
of a link (shell, solid, 1D element), this node will
be taken as a GS node.
If the connector is somewhere in space, a tempnode
is created at that position and then taken as a GS
node.

recenter GS
Reposition the initial
GS position between node GA and GB. After re-positioning,
projections are done a second time to identify the correct
node/element IDs.
Note: Only available for type CWELD (general), when the
nodetype GS (point to face) is selected.
centered quad
Perform a mesh
modification during the realization to guarantee that the CWELD
nodes will be close to the CQUAD centroids.
Specify a desired
quad size in the quad size field, or click
centered quad to access
additional centered quad settings.
centered quad tolerance
size tol
Dictates the maximum allowed deviation from
the requested centered quad size.
Size tol. is calculated using the following
formula:
The default value is set to 0.25, which
allows, for example, for a requested centered quad
size of 4 to result in a centered quad size of
5.
If a specific centered quadsize is not
requested, the tolerance will be used. The average
mesh size in that area will then be used as the
requested quadsize.
position tol
The maximum allowed distance between the cweld
node and the element centroid of the centered
quad.
Position tol. is calculated using the
following formula:
The default value is set to 0.25, which
allows, for example, for a centered quad size of 4
a distance between the cweld node and the element
centroid of < 1.
If a specific centered quadsize is not
requested, the tolerance will be used. The average
mesh size in that area will then be used as the
requested quadsize.
centered quad mesh imprint
Washer preservation settings enable washer
elements close to spot connectors to be modified,
depending on the chosen settings.
No washer preservation
Treats washer elements in the same manner as
normal elements. Washers are not protected, and
could be remeshed along with its surrounding
elements.
Preserve washer, allow remesh
Only remesh the washer elements so that a
washer can still be detected.
Preserve washer, no remesh
Do not modify the washer during imprint
realizations. Note that with this option, nearby
spot connectors might fail because of this
restriction.
feature angle
If the nodes of the mesh are not associated
with surfaces, the feature angle is needed to
identify the features, which might need to be
protected. By default, this value is set to 30.0°.
The minimum value is 10.0°. Features will not be
protected when they are close to imprint
regions.
Note: Only available for type CWELD (general), CWELD
(GA-GB ELEMID) and CWELD (GA-GB
GRIDID).
