Hi all,
I am trying to solve an intake problem using hisa solver. At first outlet is zeroGradient and after some iteration, i am giving total pressure boundary condition at the outlet. Like;

type totalPressure;
p0 uniform 120000;
gamma 1.4;

When i check the run after some iteration i am seeing that gamma value turns to 1 by openfoam. I don't understand this. What could be the reason?
