There are no shell bodies. I felt there might be some leakage so I changed the heat shield with no space as shown in image below. I did try to run the simulation with open condition but it is same error. I noticed in the error it is mentionig about, 'no space tempertaure', how can that be specified?

To run with eclosure type as open. Temperature is rising upto ~1450 degree celcius from 1400 degree celcius but starts decreasing after that. It should reach about 3300 degree celcius.Â
