Hi,all

when I calculate the free surface model,an error come out:

/Writing crash recovery file / Fatal bounds error detected --------------------------- Variable: Absolute Pressure Locale : Domain 1 maybe it is beacuse the warning :

****** Notice | 1 flat tetrahedral elements have been detected in element set 1 of the domain Domain 1. The coordinates of one of the elements are ( 0.2695E+00, 0.5125E-01, -0.1874E-01 ). If you experience robustness or accuracy problems, consider improving the mesh. Can someone give me some advice? Jason

Build a better quality mesh. Flat elements are usually fatal for solver crashes.
