Hi guys,

 

I run a injection molding in SimLab.

Then I check mesh_quality.txt file, there are 44 element failed AR criteria (range 1.01-134.48)

But when I go to Mesh>>Verify>>Quality check to cleanup element.

I compute the AR then I have the range below:

The range in mesh_quality.txt and in Quality check is different.

Moreover, in quality check for tet element, there no 4 others criteria for cleanup like in .txt file.

Please help me know how to fix these mesh in SL.

 

Best regards,

James

    Hello James,

    please notice that for the present and the future, Inspire Mold will be Altair's tool for molding. SImLab injection molding solution is still present in v 2022.3 but will probably be discontinued in the future.

    Hello James,

    First picture showcases 44 elements that are not supported. That means that the AR falls above the 50 threshold.

    It is really peculiar that SimLab does not find those elements for you to fix, but in general the numbers you display show that the mesh is distorted and of "bad" quality. I would suggest two things:

    1) Recreate the solid mesh and try to have a better distribution.

    2) See if the element quality criteria in SimLab concerns all the bodies (maybe you did not select something from your assembly).

    For reference I attach some results of my own to showcase that the results of SimLab and the Molding Solver are in accordance.

    I hope this helps,
