divergence and negative volume detected error for no reason
 

Hi

i am doing transient projectile moving inside barrel analysis.After 8600 iteration i am getting awg divergence and then negative cell volume detected error .A couple of times i stop the simulation and then started again to chech the data and change two times the calculation activities setting.Does this affects the analysis that will give error ? or what other reason that leads this stiuation ?

waiting for your valuable comments :)
