Element shape

The accuracy of Autodesk Moldflow analyses depends on the shape of meshing elements.

Ideally the triangles should be close to equilateral. Elements with too high an aspect ratio or with centroids that are too close affects the accuracy of the calculation.

Diagnostic

Visually inspect your model or use the Aspect Ratio Diagnostic tool to detect problems in the element shapes.

Solution

High aspect ratio and close centroids errors are often due to very small features, slivers or fillets.
