Hey,
I am doing Cold Flow Simulation of IC Engine in ANSYS 16.2 and facing some problems regarding it.

Divergence Detected in AMG Solver.

Negative cell volume detected.

I am doing full cycle simulation 0-720 Crank angle but after some crank angles these errors appears and solution stops.
Pressure Based solver is used and K-E RNG model is used for turbulence modeling....Please give me some suggestions and Solutions so that I can analyze it properly.
