Change the tolerance value in the mesh dialog box under mesh parameter.Play with different values.
This is one of the issue raised many times. But the developers will suggest to change the tolerance.
yea ive tried playing around with the tolerance but the tolerance value i set is not what solidworks meshes it to and just changes it back to the default setting for some reason.
this is what i got back from soldworks:
When running a static analysis with a mesh containing shell elements, this error message appears at
the beginning of the analysis.
The error message is displayed because the solver detected one or more very, very sliver shell
elements. This can happen if you have surfaces that have knife edges and sliver faces. The reason
being that based on the mesh size that you are using, one or several elements with a very high
aspect ratio could have formed on these geometric entities. The area of such elements is almost
To get around the issue, you can do this:
1. First plot the aspect ratio of the entire mesh. You can do this by right clicking on the mesh
and selecting Create Mesh Plot.
2. Then select Aspect ratio and click OK to generate the plot.
3. Identify the regions that have elements with a very high aspect ratio.
4. Apply mesh controls to these regions.
5. Re-mesh the model and run the analysis.
The error message should go away.
You can also plot the mesh and do a List Selected on the mesh plot. This will list all the shell
elements of the surface you will select. Since the element are sorted by number, you can easily find
the element which number is given in the message. You will then identify the area of the model
when the mesh causes a problem. then, either apply a mesh control or edit the geometry to
improve the quality of the mesh that will be generated.
