Hello.

I want to simulate the forging process of a complex part using the Explicit solution in Abaqus. Due to the complexity of the geometry, I have to use Tet elements. But while solving it, I come across an error that says that a number of elements have a negative or zero mass or volume.

Is there a solution that during the solution, if the volume of the element becomes zero, the element is automatically removed and the solution continues?

Thanks.
