Hi all,
I am running free surface flow around a vertical surface piercing cylinder. I am having no trouble for longer wavelengths (smaller diameter to wavelength ratio) but am having a lot of trouble for a short wavelength (wavelength = 2.4 m, diameter = 0.5, waveheight = 0.25). I am trying to use minimum 50 cells per wavelength and 8 per wave height, which have been plenty for previous simulations. My constant/waveProperties.input file looks like this: Code:
/*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 1.5 | | \\ / A nd | Web: http://www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; object environmentalProperties; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // seaLevel 0.00; // A list of the relaxation zones in the simulation. The parameters are given // in <name>Coeffs below. relaxationNames (inlet outlet); initializationName outlet; //pName p_rgh; inletCoeffs { //waveType potentialCurrent; //U ( 0.6 0 0 ); //Tsoft 0; waveType stokesFirst; // Regular waves depth 2.5; // Water Depth period 1.25; // Wave period phi 0.00000; // Phase direction (1.0 0.0 0.0); // Direction of incoming waves height 0.25; // Wave height in meters Tsoft 0.0; relaxationZone { relaxationScheme Spatial; relaxationShape Rectangular; beachType Empty; alphaCoefficient 1; relaxType INLET; startX ( -7.2 -3.5 0.0); endX ( -3.6 3.5 0.0); orientation (1.0 0.0 0.0); } }; outletCoeffs { waveType potentialCurrent; U (0 0 0); Tsoft 0; relaxationZone { relaxationScheme Spatial; relaxationShape Rectangular; beachType Empty; alphaCoefficient 1; relaxType OUTLET; startX ( 4.5 -3.5 0.0); endX ( 7.2 3.5 0.0); orientation (1.0 0.0 0.0); } }; // ************************************************************************* // Any advice on what could be causing these problems?? |
