high temperature jet flow converge issue.
 
2 Attachment(s)
hi, i use rhoPisoFoam to simulate high temperature (10000) jet flow out of a nozzle to air (300k), I have converge issue at the nozzle exit. I found that DpDt term had zigzag problem, see pics. For low temperature, it is ok.

Can any one give me some hint.
