Invalid Spot Weld
The run cannot be completed because the spot weld size is too large, or the material at the spot weld location is missing due to optimization.
Figure 1. Bad Example: Spot weld diameter is too small in relation to the mesh size
Figure 2. Good Example: Spot weld diameter is similar to the mesh size
In cases where you have a spot weld on a flange, you can also get this error if the diameter of the spot weld is too large in relation to the flange. To fix this issue, decrease the diameter of the spot weld.
