[Nektar-users] PressureOutflow boundary condtions

Hi all! I want to give static pressure on my outlet, p0eInf is the value that i have defined in parameters . Can you help me check out my example? By the way, i don't know how to set 'WallAdiabatic' boundary conditions ,can you help me check out my example? Sometimes when i run the calculation,it will report an error called 'vacuum is generated by given data'.If i change the TimeStep , it will calculate some steps.How to explain it? Looking forward to your replay!
