Hi Foamers!
I wanted to use this opensource solver https://gitlab.com/Jose_Moreno/openfoam_dom I have compiled it successfully on openfoam7 but when I try to use it for an application, I get this error: /*---------------------------------------------------------------------------*\ ========= | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox \\ / O peration | Website: https://openfoam.org \\ / A nd | Version: 7 \\/ M anipulation | \*---------------------------------------------------------------------------*/ Build : 7-1ff648926f77 Exec : MultiRegionRadiationFoam Date : Oct 29 2021 Time : 14:25:46 Host : "CFD" PID : 909686 I/O : uncollated Case : /home/cfd/openfoam7/tutorials/heatTransfer/MultiRegionRadiationFoam nProcs : 1 sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). fileModificationChecking : Monitoring run-time modified files using timeStampMaster (fileModificationSkew 10) allowSystemOperations : Allowing user-supplied system call operations // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create fluid mesh for region air for time = 0 *** Reading fluid radiation properties for region air Selecting radiationModel DORT Selecting phase Function Model HenyeyGreenteinsPhaseFunction Selecting extintionModel greyConstExt Solving optics... quadrature : Allocated 16 rays with average orientation: ray0 : omega : 0.785398 dir : (0.19509 0.980785 6.12323e-17) ray1 : omega : 0.785398 dir : (0.55557 0.83147 6.12323e-17) ray2 : omega : 0.785398 dir : (0.83147 0.55557 6.12323e-17) ray3 : omega : 0.785398 dir : (0.980785 0.19509 6.12323e-17) ray4 : omega : 0.785398 dir : (0.980785 -0.19509 6.12323e-17) ray5 : omega : 0.785398 dir : (0.83147 -0.55557 6.12323e-17) ray6 : omega : 0.785398 dir : (0.55557 -0.83147 6.12323e-17) ray7 : omega : 0.785398 dir : (0.19509 -0.980785 6.12323e-17) ray8 : omega : 0.785398 dir : (-0.19509 -0.980785 6.12323e-17) ray9 : omega : 0.785398 dir : (-0.55557 -0.83147 6.12323e-17) ray10 : omega : 0.785398 dir : (-0.83147 -0.55557 6.12323e-17) ray11 : omega : 0.785398 dir : (-0.980785 -0.19509 6.12323e-17) ray12 : omega : 0.785398 dir : (-0.980785 0.19509 6.12323e-17) ray13 : omega : 0.785398 dir : (-0.83147 0.55557 6.12323e-17) ray14 : omega : 0.785398 dir : (-0.55557 0.83147 6.12323e-17) ray15 : omega : 0.785398 dir : (-0.19509 0.980785 6.12323e-17) Time = 0.0005 Solving for fluid region air #0 Foam::error: ![]() #1 Foam::sigSegv::sigHandler(int) at ??:? #2 ? in "/lib/x86_64-linux-gnu/libc.so.6" #3 Foam::radiation::blackBodyEmissionRev::EbDeltaLamb daT(Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&, Foam::Vector2D<double> const&) const at ??:? #4 Foam::radiation::blackBodyEmissionRev::correct(int , Foam::Vector2D<double> const&) at ??:? #5 Foam::radiation: ![]() #6 ? in "/home/cfd/OpenFOAM/cfd-7/platforms/linux64GccDPInt32Opt/bin/MultiRegionRadiationFoam" #7 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #8 ? in "/home/cfd/OpenFOAM/cfd-7/platforms/linux64GccDPInt32Opt/bin/MultiRegionRadiationFoam" Segmentation fault (core dumped) I have tried to copy a sample solver ,renamed it and used it in a tutorial to see if the error is reproduced with every new solver but the error could not be reproduced for the copied openfoam solvers. Please help me find the source of error. Thanks! |

The second line of your error gives you some hint
Quote:
The next few lines of the error gives you the idea about the EXACT locations within the code where this might be happening Quote:

I have seen the original location of error. It points out to the following piece of code in blackBodyEmissionsRev.C: Code:
Foam::tmp<Foam::volScalarField> Foam::radiation::blackBodyEmissionRev::EbDeltaLambdaT ( const volScalarField& T, const Vector2D<scalar>& band ) const { tmp<volScalarField> Eb ( volScalarField::New ( "Eb", physicoChemical::sigma*pow4(T) ) ); if (band != Vector2D<scalar>::one) { scalarField& Ebif = Eb.ref(); forAll(T, i) { Ebif[i] *= fLambdaT(band[1]*T[i]) - fLambdaT(band[0]*T[i]); } volScalarField::Boundary& EbBf = Eb.ref().boundaryFieldRef(); forAll(EbBf, patchi) { fvPatchScalarField& EbPf = EbBf[patchi]; if (!EbPf.coupled()) { const scalarField& Tpf = T.boundaryField()[patchi]; forAll(EbPf, facei) { const scalar T1 = fLambdaT(band[1]*Tpf[facei]); const scalar T2 = fLambdaT(band[0]*Tpf[facei]); EbPf[facei] *= T1 - T2; } } } } return Eb; } ![]() |
