Re: Dynamic Mesh...new problem
 

Hi,

i have a new problem.

i build a mesh and use the dyn. Mesh Module, 6DOF with layering.

When i start iterate, the solver runs. After 78 time steps i get this message:

Updating solution at time level N... done.

Updating mesh at time level N...

WARNING: non-positive volumes exist.

Error: Update-Dynamic-Mesh failed. Negative cell volume detected. Error Object: ()

and the solver stops. At the frames can i see, that the box started to fall.

What kind of problem is it? The "start mesh" was grid/checked and ok.

thanks and best regards
