Hello
I have some code that worked in OpenFoam-1.4.1 , but i can't seem to get it working on rhoCentralFoam. I am running a very simple test 1)Geometry is just a rectangular channel. 2)If i specify all variables at inlet(as in supersonic inflow), and extrapolate all values(as in supersonic outlet), everything is fine. As expected there is no change in any flow parameters 3)If i change the bc's to subsonic inflow and outflow, all hell breaks lose. I specify p,T on inlet. U is computed at inlet using the keyword pressureInletVelocity, At outlet i specify p and extrapolate T,U using the zeroGradient keyword. However even in such a simple case i get a floating point exception from sqrt Could some one tell me what i am doing wrong? Or is this a bug? I have been looking at this for the last 3 days, with no results Thanks Srinath |
