Hi everybody,

can anybody help me to choose the appropriate solver and the boundary conditions for this problem:

2D-problem - a tube with XYZ 200m infinite 10m
inlet pressure at X=0: 2 bar abs
outlet pressure at X=200: 1bar abs
the velocity in the tube is probably several m/s

I want to calculate the streamlines - o.k. - but in the end I need the force on the walls at Z=0 and Z=10

who can help me ?

Thanks in advance Stefan
