hello,
i am extremely new to OpenFOAM, im trying to make my first geometry and mesh using blockMesh. i just edited the blockMeshdict file from the cavity case for my geometry. im trying to create a geometry for a simple 2D flat plate in laminar flow case plate is 1m and the height of domain is 0.5m -plate at the bottom, inlet on left , outlet to the right and farfield on top if the errors seems very basic, plz forgive , this is only my 3 day on openFOAM this is how i edited the blockmeshdict file - convertToMeters 1; vertices ( (0 0 0) (1 0 0) (1 0.5 0) (0 0.5 0) (0 0 0.1) (1 0 0.1) (1 0.5 0.1) (0 0.5 0.1) ); blocks ( hex (0 1 2 3 4 5 6 7) (50 60 1) simpleGrading (1 70 1) ); edges ( ); boundary ( inlet { type patch; faces ( (0 4 7 3) ); } outlet { type patch; faces ( (1 2 6 5) ); } farfield { type symmetryPlane; faces ( (3 7 6 2) ); plate { type wall; faces ( (1 5 4 0) ); } frontAndBack { type empty; faces ( (0 3 2 1) (4 5 6 7) ); } ); mergePatchPairs ( ); // ************************************************** *********************** // and this is the error i get... --> FOAM FATAL IO ERROR: "ill defined primitiveEntry starting at keyword 'boundary' on line 41 and ending at line 94" file: /media/sf_OpenFOAM/flatplate/constant/polyMesh/blockMeshDict at line 94. From function primitiveEntry::readEntry(const dictionary&, Istream&) in file lnInclude/IOerror.C at line 132. FOAM exiting all help is greatly appreciated, thanks in advance, |

Good morning Joseph,
You are missing a curly bracket, }, at the end of your farfield definition. Kind regards, Niels

Thank you., i knew it must be something stupidly simple like that.
it worked out well. so went ahead and setup the rest of the case. (by my understanding standards ) but now have run into a diff prob. im trying to run the flat plate case using icoFoam for 1000 iterations with a deltaT of 0.01, so total 10 secs. so my simulation runs until 1.66 secs i.e. 166 iterations. then at 1.67 i get the following error and dump msg.. ive included the msg frm 1.66 secs for ref if needed.. Time = 1.66 Courant Number mean: 1.03658e+89 max: 1.19227e+91 DILUPBiCG: Solving for Ux, Initial residual = 0.99532, Final residual = 15.6817, No Iterations 1001 DILUPBiCG: Solving for Uy, Initial residual = 0.998739, Final residual = 3.49624, No Iterations 1001 DICPCG: Solving for p, Initial residual = 1, Final residual = 7.47581, No Iterations 1001 time step continuity errors : sum local = 2.97164e+93, global = -1.6172e+91, cumulative = -1.61721e+91 DICPCG: Solving for p, Initial residual = 0.984306, Final residual = 3.82589, No Iterations 1001 time step continuity errors : sum local = 7.6204e+95, global = 2.29239e+93, cumulative = 2.27621e+93 ExecutionTime = 9.87 s ClockTime = 16 s Time = 1.67 Courant Number mean: 1.5404e+96 max: 1.81873e+98 #0 Foam::error:rintStack(Foam::Ostream&) in "/opt/openfoam221/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #1 Foam::sigFpe::sigHandler(int) in "/opt/openfoam221/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #2 in "/lib/x86_64-linux-gnu/libc.so.6" #3 double Foam::sumProd<double>(Foam::UList<double> const&, Foam::UList<double> const&) in "/opt/openfoam221/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #4 Foam::PBiCG::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const in "/opt/openfoam221/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #5 in "/opt/openfoam221/platforms/linux64GccDPOpt/bin/icoFoam" #6 in "/opt/openfoam221/platforms/linux64GccDPOpt/bin/icoFoam" #7 in "/opt/openfoam221/platforms/linux64GccDPOpt/bin/icoFoam" #8 in "/opt/openfoam221/platforms/linux64GccDPOpt/bin/icoFoam" #9 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #10 in "/opt/openfoam221/platforms/linux64GccDPOpt/bin/icoFoam" Floating point exception (core dumped) I apologize if its again something stupid. like i mentioned in my previous post, im very new and trying to learn on my own... im not completely confident about my case setup also. Thanks a lot and i appreciate your time... |

Hi every one!
Would any one please help me with similar problem? I have attached my blockMesh file and have an error like the following when running blockMesh: --> FOAM FATAL IO ERROR: "ill defined primitiveEntry starting at keyword 'blocks' on line 299 and ending at line 1753" Thanks! |
