Scan-and-Solve for Rhino

Simulate Early, Simulate Often... In Rhino

I'm running simulations on a thin-walled tank of circular cross-section.  Overall tank diameter is 56 inches, and skin thickness is 0.063 inches.  Of course, higher resolution yields better results, but I get a persistent "banding" of higher than expected stresses, and they appear localized (in the bands) where intuitively I believe there should be no such localization.

My guess is that this might be caused by variations in the skin thickness as represented by the mesh. Is there a setting that will cause it to generate a mesh of more uniform thickness - or am I even close as to my guess on this?

You are analyzing a very thin shell model using 3D elements in Scan&Solve.  It is possible that your resolution is not high enough to deal with such a high size/thickness ratio, as explained in the documentation.  But it is difficult to say for sure without looking at your problem and solution more carefully.   Feel free to send us your model (with boundary conditions) at support@intact-solutions.com if you would like us to look further into the issue.
