I ran the simulation with supersonic /inintial gauge pressure zero but I am not able to achieve proper results. When i ran the simulation with the condition that It only had one fluid domain (air flow thourgh C-D nozzle) it ran perfectly with inlet alternatively  as mass flow inlet and pressure based inlet, in case of mass flow inlet condition was the exact same value as achieved with the analytical results and in case of pressure based inlet the values were same as mentioned above for air flow but as soon as i added the solid domain above it to monitor the heat transfer, the results detoriated. Kindly guide what might be the probelm.
