Hello openFoam users,
i just started evaluating this promissing code and as usual in the beginning i have a problem. I just wanted to run the nacaAirfoil example in sonicTurbFoam with a free-stream velocity below sonic-speed (Ma<1) so that the velocity has to go supersonic only in a small area. But the solver is complaining that the free-stream Mach-Number must not be below 1: --> FOAM FATAL ERROR : MachInf < 1.0, free stream must be supersonic Is there a way to handle compressible flow for subsonic inlet conditions? Best regards, Klaus |
You have chosen a supersonicFr
You have chosen a supersonicFreestream BC but specified a sub-sonic flow, why not choose a standard fixedValue inlet or inletOutlet condition?

Ups,
you got me. I was hasty and i missed to change this entry in the inlet condition of U. From: INLE1 { type supersonicFreeStream; pInf 100000; TInf 300; UInf (60.0 14.816 0); } To: type fixedValue; value uniform (60.0 14.816 0); I also changed p now. From: OUTL2 {type pressureTransmissive; pInf 100000; lInf 1; } To: OUTL2 { type fixedValue; value uniform 100000; } I will try it soon. Thanks for the quick reply and for all your effort with the software, Klaus |
