Good day,
I am at a loss to the magnitude of different issues I am getting with openFoam this week. In this case; I am trying to specify a rotating inlet to a 1/8th section of an axial flow fan. I am working in the rotating frame of reference, so would like my inlet velocity to be rotating about the axial direction (y direction in my case). The goal for now is to troubleshoot why my solution is diverging by analyzing a potentialFoam case, so only my U file is of importance. It is set up as such: Code:
/*--------------------------------*- C++ -*----------------------------------*\ ========= | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox \\ / O peration | Website: https://openfoam.org \\ / A nd | Version: 5 \\/ M anipulation | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class volVectorField; location "0"; object U; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 1 -1 0 0 0 0]; internalField uniform (0 -10.96 0); boundaryField { inlet { type cylindricalInletVelocity; origin (0 0 0); axis (0 1 0); radialVelocity constant 0; axialVelocity constant -10.96; rpm constant 750; value (0 0 0); } outlet { type zeroGradient; } blade { type fixedValue; value uniform (0 0 0); } left { type cyclicAMI; } right { type cyclicAMI; } shroud { type symmetry; } hub { type symmetry; } } // ************************************************************************* // I'm at a loss for what to do here, so any help would be appreciated. Regards |
