Cweld (General)

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:

$\frac{\text{absolute value}\left(\text{current quadsize - requested quadsize}\right)}{\text{requested quadsize}}$

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:

$\frac{\text{absolute distance}\left(\text{center of current quad - cweld node}\right)}{\text{position tolerance}\ast \text{requested quadsize}}<1$

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.

Figure 3. Mesh Prior to Applying the Centered Quad Mesh Imprint Option

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.

Figure 4. Mesh with Centered Quad Mesh Imprint Set to No Washer Preservation

Preserve washer, allow remesh

Only remesh the washer elements so that a washer can still be detected.

Figure 5. Mesh with Centered Quad Mesh Imprint Set to Preserve Washer, Allow Remesh

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.
