hi guys
we are working on Fsi project, and we used icofsifoam for solve, and we encountered with this error after mesh & boundary generation, so can anyone help us to what we should do about this error error: /*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM Extend Project: Open source CFD | | \\ / O peration | Version: 1.6-ext | | \\ / A nd | Web: www.extend-project.de | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : 1.6-ext-a0e4ecb4d630 Exec : icoFsiFoam Date : Jul 28 2013 Time : 13:34:36 Host : soheil-Aspire-5755G PID : 6213 Case : /home/soheil/Desktop/myCase/fluid nProcs : 1 SigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create dynamic mesh for time = 0 Selecting dynamicFvMesh dynamicMotionSolverFvMesh --> FOAM Serious Error : From function IOobject::readHeader(Istream&) in file db/IOobject/IOobjectReadHeader.C at line 90 Reading "/home/soheil/Desktop/myCase/fluid/constant/polyMesh/boundary" at line 1 First token could not be read or is not the keyword 'FoamFile' Check header is of the form: /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM Extend Project: Open source CFD | | \\ / O peration | Version: 1.6-ext | | \\ / A nd | Web: www.extend-project.de | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class IOobject; location "constant/polyMesh"; object boundary; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // --> FOAM Serious Error : From function IOobject::readHeader(Istream&) in file db/IOobject/IOobjectReadHeader.C at line 90 Reading "/home/soheil/Desktop/myCase/fluid/constant/polyMesh/boundary" at line 1 First token could not be read or is not the keyword 'FoamFile' Check header is of the form: /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM Extend Project: Open source CFD | | \\ / O peration | Version: 1.6-ext | | \\ / A nd | Web: www.extend-project.de | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class IOobject; location "constant/polyMesh"; object boundary; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // --> FOAM FATAL ERROR: Cannot find file "boundary" in directory "constant/polyMesh" From function Time::findInstance(const fileName&, const word&, const IOobject::readOption) in file db/Time/findInstance.C at line 148.

read the error to solve the problem, solver is looking for the file name "boundary", but it can not find it in directory "constant/polyMesh", so you need to add this file to your constant/polyMesh

Hi ,
I try to solve my case with icoFsiFOAM solver , but in my geometry this eroor accur when try to solve it : ..... Moving mesh time step continuity errors : sum local = -92209, global = 1.98903, cumulative = 2.86326 CG: Solving for p, Initial residual = 0.999957, Final residual = 7.0708e-07, No Iterations 526 CG: Solving for p, Initial residual = 0.999109, Final residual = 0.000723223, No Iterations 1000 Moving mesh time step continuity errors : sum local = 2.07627e+14, global = 2.26112e+10, cumulative = 2.26112e+10 Floating point exception (core dumped) please help me to solve it...! |

it diverges you may want to try smaller timeStep or reduce your residual at fvSolution or increase your correctors in PISO
