high pressure on tank

Martin_Sz · January 20, 2015, 03:05

Hello
I have problem to solve a high pressure tank.
I need to do this on transient simulation.
I have a tank with 100 Bar (initialization) pressure inside. One outlet with 101300 Pa.
The gas is N2 STP. I need to determinate mass flow on outlet.
When I do this with N2 STP and total energy I receive overflow cpx handler.
How to solve this problem ?
Best regards

Why not just use an oriface flow equation and a simple ODE solver? This does not sound like a CFD question to me.

thanks Glenn
I found good calculator for this problem
