i have written three pressure BC.and then tried to do by groovyBC.although it seems equivalent to others it don't work.
if this problem resolve i think the trouble is removed. fixedValue p:OK Code:
type fixedValue; value uniform 1023382.5; Code:
type totalPressure; rho none; psi psi; phi phi; p0 1023382.5; gamma 1.4; Code:
type groovyBC; fractionExpression "1"; valueExpression "1023382.5/pow(1+(1.4-1)*magSqr(U)/(2*1.4*287.14*T),3.5)"; value uniform 3523382.5; Code:

the whole p is:
Code:
FoamFile { version 2.0; format ascii; class volScalarField; object p; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [1 -1 -2 0 0 0 0]; internalField uniform 3523382.5;//1823382.5 boundaryField { right { /*type fixedValue; value uniform 1023382.5;*/ /*type totalPressure; rho none; psi psi; phi phi; p0 1023382.5; gamma 1.4;*/ type groovyBC; fractionExpression "1"; valueExpression "1023382.5/pow(1+(1.4-1)*magSqr(U)/(2*1.4*287.14*T),3.5)"; value uniform 3523382.5; } left { type zeroGradient; } walls { type zeroGradient; } empty { type empty; } } I have to write BC in groovyBC form because of more complicated main case I have to solve. thanks very much.please answer rapidly. |

There are several issues:
Your BC may be giving the error when a boundary condition is corrected and has a T == zero for some reason. Honestly, without more information this is the best i can do with solving your issue...but its an educated guess at this point. #OFProtip Last edited by chegdan; March 5, 2013 at 19:24. |

thanks.T isn't zero and also its same for all three tests.but only in groovy it occurs.

did you try another time integration scheme? I see a backwardDdtScheme in your error message and there may be something happening there. Also, just to prove that its not the T in the denominator, change your value expression to
Code:
valueExpression "1023382.5/pow(1+(1.41)*magSqr(U)/(2*1.4*287.14*T + 1e-8),3.5)"; |

i changed time scheme to Euler and changed T but error persists.initial U is zero and i changed it but the error didn't change
these are variable BC's: p: Code:

thanks for your effort to help dear Daniel.
It was because of new groovyBC.I changed to old version and it answer now. |

OK, it is indeed your BC setup. I don't have the time to set this up for you, but i have some suggestions.
Good luck EDIT: read your new post that just mystically appeared....glad you figured it out Last edited by chegdan; March 6, 2013 at 10:26. Reason: read new post |

a question occur to me that I'm curious about.
when I set BC for U to zeroGradient or: Code:
right { type groovyBC; fractionExpression "0"; gradientExpression "vector(0,0,0)"; } but when I set it to: Code:
right { type groovyBC; fractionExpression "1"; valueExpression "internalField(U)";//vector(internalField(U).x,0,0) } Code:

besides that, the velocity on outward flow should be read from inside implicitly and only pressure should be set there as a known value otherwise error will arise due to instability. I hope these explanations be what you asked about.

Hi,
I also have this problem. But I don't know how to fix it. --> FOAM Warning : From function Foam::scalar Foam::janafThermo<EquationOfState>::limit(Foam::sc alar) const [with EquationOfState = Foam:erfectGas<Foam::specie>; Foam::scalar = double] in file /home/pawan/OpenFOAM/OpenFOAM-v1812/src/thermophysicalModels/specie/lnInclude/janafThermoI.H at line 117 attempt to use janafThermo<EquationOfState> out of temperature range 200 -> 5000; T = -388.868 --> FOAM Warning : From function Foam::scalar Foam::janafThermo<EquationOfState>::limit(Foam::sc alar) const [with EquationOfState = Foam:erfectGas<Foam::specie>; Foam::scalar = double] in file /home/pawan/OpenFOAM/OpenFOAM-v1812/src/thermophysicalModels/specie/lnInclude/janafThermoI.H at line 117 attempt to use janafThermo<EquationOfState> out of temperature range 200 -> 5000; T = -111.631 min/max(T) = 200, 1742.55 Any suggestion? I read that the problem could be about different values in BC in the Internal Field and in the neighbor cells, but i did not understand exactly what it means! |
