Hi i am newbie in openfoam, i did draw a simple geometry in solidworks, i did mesh it with salome 8.4 NETGEN 1D-2D-3D (Image 1) and i saved it as a UNV file. Then i import openfoam7 with ideasUnvToFoam utility and i reorganize my boundarys like below downside. When i checkMesh there isn't any error but when i run my case with icoFoam i get the error which below downside. At first, code running like 5-10 second. How can i fix this, any suggestion?
(This case based on, incompressible/icoFoam/elbow tutorial.) Code:
//boundary conditions 6 ( wall-8 { type wall; inGroups List<word> 1(wall); nFaces 1424; startFace 210272; } wall-4 { type wall; inGroups List<word> 1(wall); nFaces 892; startFace 231346; } velocity-inlet-5 { type patch; nFaces 708; startFace 229924; } velocity-inlet-6 { type patch; nFaces 894; startFace 232238; } pressure-outlet-7 { type patch; nFaces 714; startFace 230632; } frontAndBackPlanes { type empty; inGroups List<word> 1(empty); nFaces 18228; startFace 211696; } ) Code:
//U file dimensions [0 1 -1 0 0 0 0]; internalField uniform (0 0 0); boundaryField { wall-4 { type noSlip; } velocity-inlet-5 { type fixedValue; value uniform (1 0 0); } velocity-inlet-6 { type fixedValue; value uniform (0 3 0); } pressure-outlet-7 { type zeroGradient; } wall-8 { type noSlip; } frontAndBackPlanes { type empty; } } Code:
//p file dimensions [0 2 -2 0 0 0 0]; internalField uniform 0; boundaryField { wall-4 { type zeroGradient; } velocity-inlet-5 { type zeroGradient; } velocity-inlet-6 { type zeroGradient; } pressure-outlet-7 { type fixedValue; value uniform 0; } wall-8 { type zeroGradient; } frontAndBackPlanes { type empty; } } Code:

Setup problem, very likely.
Reduce time-step 100 times, or do use adjustableTimeStep.
