change the "extrusion" value in Trim panel, and try again.
Or,adjust the 2d template, and then try again. |

1.Based on my experience, if your 3d template is perfect, to adjust the value of extrusion or set zero for this value is always possible to get rid of the negative volume problem.
2. decrease the time step, so the courant number will be reduced. |
