Hi, I am working with a 3-D incylinder problem,on turbulence modeling.I imported the CAD geometry of a simple arrangement of piston and cylinder, from the CAD software and completed the meshing in Gambit, when I tried to run it the Fluent solver with Dynamic mesh model,I am unable to proceed after certain degree of crank angle, the following eror occured:Unable to update dynamic mesh at 370 degree crank angle becasue of negative volume. This error occured when I solved the mesh motion set up in fluent.

Could any one please advice on this,how to solve this problem?

Thanks
