Hi all,
i'm trying to simulate an axisymmetric jet in OpenFoam using the pisofoam solver......when i run the solver....after one or two time steps ,it gives an error............i'm providing u with my blockMeshDict file and the error............... /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.1.0 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; object blockMeshDict; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // convertToMeters .001; vertices ( (0 0 0)//0 (-10 0 0)//1 (-10 4.9952 -.218166)//2 (0 4.9952 -.218166)//3 (-10 4.9952 .218166)//4 (0 4.9952 .218166)//5 (2000 4.9952 .218166)//6 (2000 4.9952 -.218166)//7 (2000 0 0)//8 (0 998.096 -43.633)//9 (0 998.096 43.633)//10 (2000 998.096 43.633)//11 (2000 998.096 -43.633)//12 ); blocks ( hex (3 7 6 5 0 8 8 0) (50 1 50) simpleGrading (1 1 1) hex (9 12 11 10 3 7 6 5) (50 1 50) simpleGrading (1 1 1) ); edges ( ); patches ( patch inlet ( (0 3 5 0) ) patch outlet ( (8 7 6 8) (7 12 11 6) ) wall upperwall ( (3 9 10 5) ) wedge front ( (0 5 6 8) (5 10 11 6) ) wedge back ( (3 7 12 9) (0 8 7 3) ) empty bases ( (0 8 8 0) ) ); mergePatchPairs ( ); the error is.........
