FATAL ERROR: X7060
|
Element(s) were detected with a negative volume that were not deleted from the model.
|
|
Cause:
|
Excessive distortion of the finite element mesh has caused one or more elements to have a negative volume, which invalidates their results. This case happens when nonsensical loads have been applied to the model that cause it to deform beyond any reasonable expectations. While Autodesk Explicit has a large-deformation formulation that allows extremely large strains, there are limits to how far you can distort a model (example: you cannot turn a part "inside-out").
|
|
Action:
|
Check the loads and boundary conditions to see if they are reasonable, then defining appropriate element deletion criteria can often fix this problem.
