Lewis Lee New Member Qinan Li Join Date: Jul 2022 Posts: 1 Rep Power: 0	I recently used FLUENT to simulate the change of gas pressure with temperature in a confined space. The temperature increase is caused by the combustion of the external gas. The results show that the temperature of the gas in the container has increased significantly, but the pressure is almost unchanged, and the gas density has decreased. I have defined it as an ideal gas in the material, and turned on the compressible option, please tell me how to solve this problem
