icem 3d mesh for compressible flow with combustion
 
Hi All,

Has anyone created a tetra mesh in icemcfd 11.0 for compresible flow simulation with combustion in Fluent? I have done it but i keep having problems with convergence. For the cold flow, the steady flow residuals drops nicely and but when i switch to hot flow, the residuals begin to fluctuate......it is not the case if it is incompressible. The residuals for the fuel especially are showing sharp fluctuations. Any thoughts on why this is happening?

Counting on your assistance.

Jimmy
