Has anyone ever modeled a rotating detonation engine combustor with COMSOL before? I keep getting errors in my RDE combustor. Something about tcs.T even though it is coupled with heat transfer in fluids.

Mass fractions Division by zero. - Function: / Failed to evaluate expression. - Expression: dvol_spatial((1/comp3.tcs2.T)(comp3.tcs2.d(comp3.tcs2.DT_w2H2(((comp3.tcs2.nxmean(d(comp3.tcs2.T,x)))+(comp3.tcs2.nymean(d(comp3.tcs2.T,y))))+(comp3.tcs2.nzmean(d(comp3.tcs2.T,z))))))) Failed to evaluate Jacobian of expression. - Expression: (comp3.tcs2.DT_w2H2(comp3.tcs2.nxmean(d(comp3.tcs2.T,x))+comp3.tcs2.nymean(d(comp3.tcs2.T,y))+comp3.tcs2.nzmean(d(comp3.tcs2.T,z)))test(comp3.w2H2)comp3.tcs2.d/comp3.tcs2.T)(dvol_spatial)
