I want to analyze pressurised gas filled solid container cooled by water flow inside CFX workbench. I have specified two fluid,solid zone. In gas fluid is air and other fluid is water. Both the fluid is with isolated physics. The water zone is having in/outlet. the ref pr. is 1.013e5Pa. Both gas and solid is having source of heat. On CFD-Post, the pr. variation is there for water but for gas zone it is zero with local pressure.however, temp. variation is there inside gas. Although on heat, the pressure of gas should increase. why I can't see pressure variation inside gas? Any special setting is there?
