Problems when change the boundary conditions in rhoSimplicFoam tutorial example
Hello, Foamers;
I just begin to use OpenFOAM to do my thesis. Since my problem is a compressible case, so I'd like to choose the rhoSimplecFoam solver to solve it. In the tutorial example offered in the rhoSimplecFoam solver, it gives a mass flowrate inlet condition and pressure outlet condition. However, in my case, it should be a total pressure inlet condition and pressure outlet condition. Problem comes as I changed the boundary conditions of U and P after 3 iterations. The error messages are as following: Quote:
P Code:
dimensions [1 -1 -2 0 0 0 0]; Code:
dimensions [0 1 -1 0 0 0 0]; Endless appreciation if any foamers can help. Sylvain |
Hi Sylvain,
I think you should change your pressure boundary condition for the outlet to either a fixed static pressure or to outletInlet instead of inletOutlet. Look up their differences in the sourcecode! Some hints: Code:
$> cd $FOAM_SRC You may also need to ramp your total pressure at the inlet over several iterations. I think some examples may be found on the forum. Regards, Tom |
