However, I got this error after several itterations in mesh motion: Updating mesh to time 1.98750e-02 (step = 00477) (crank-angle = 598.50)... WARNING: non-positive volumes exist. Dynamic Mesh Statistics: Minimum Volume =-9.18062e-010 Maximum Volume =2.09744e-006 Maximum Cell Skew =5.96430e-001 (cell zone 7) Warning: negative cell volume detected! Error: Update dynamic mesh failed. Negative cell volume detected. Error Object: () How can I fix this? thank in advance
