Dear all,
I have compiled the sources of 1.5-dev (snapshot 2009-02-02 from powerlab) using the system gcc-compiler (ver. 4.2.1) on my openSuSE 10.3 (64-bit). Compilation gave no errors and foamInstalationTest also says that all is OK. Now, when I run the damBreakWithObstacle tutorial with interDyMFoam, the calculation starts, but I obtain the following error: Starting time loop Courant Number mean: 0 max: 0 velocity magnitude: 0 deltaT = 0.00117647 Time = 0.00217647 Selected 192 cells for refinement out of 32256. Refined from 32256 to 33600 cells. Selected 0 split points out of a possible 192. Execution time for mesh.update() = 0.19 s time step continuity errors : sum local = 1.83574, global = 0, cumulative = 0 keyword agglomerator is undefined in dictionary "" file: from line 0 to line 0. From function dictionary::lookupEntry(const word& keyword) const in file db/dictionary/dictionary.C at line 213. FOAM exiting I have the recompiled the application interDyMFoam with gcc-4.3.1, but I again get the same error. Does this mean that the fvSolution dictionary cannot be read? Can anybody help on this? Best Regards, Edin. |

Hi Edin,
I got the same problem. The solution is to change in system/fvSolution: preconditioner GAMG { ... to preconditioner { type GAMG; ... Best regards, Hannes

Thanks Hannes.
I have already done that. I have also changed the dynamicMeshDict as follows: lowerRefineLevel 0.01; upperRefineLevel 0.99; maxRefinement 3; maxCells 5000000; But now the calculation starts and it crashes after several time steps on floating point exception. Did you have same experiences? Best regards, Edin. |

Hello everybody
We are used OpenFOAM1.5.1 with suse11, 64bits, and tried to refinement our mesh, we are used dynamicRefineMeshDict and didn`t understand some parameter like: // All points are candidates for unrefining unrefineLevel 10; nBufferLayers 1; // Maximum refinement level (starts from 0) maxRefinement 2; // Maximum cell limit (approximate) maxCells 50000; (default values in interDyMFoam) we are change it´s, and noticed some different respect to default values, eg, maxRefinement 10; maxCells 500000 but when we changes unrefineLevel ; nBufferLayers we didn`t see any difference in refinement mesh. Somebody could to explained us what`s it means this parameters? we are appreciate any comments. Sonia and Ana |

Hi!
As I got mad, trying to refine the mesh, I started searching the web for a solution. Unfortunatelly I couldn't find any. At least some of you got the same problem as I did. I also have the same problem as Edin. My mesh is refining, but afterwards it ends with a floating point exception. Sometimes it works for a few iterations if the changes are not very big (only 10-40 cells) but if it is 100 cells in total or more: goodbye. :-( Btw, I wouldn't suggest to use GAMG to solve anything, because there is that agglomerator problem, which always hangs up on my mesh (due to some unequal field sizes). PCG got a better result. Not it is "only" the floating point error. So does anyone have any experience with that problem? Btw: I changed the interDyMFoam solver to be able to calculate multiphases (copied from the multiphaseInterFoam solver); maybe the problem is in the incompatibility? |

Dear Foamers,
I am trying to test the GAMG presconditioner in OF1.5 for my pressure and continue to get Istream errors. Does anyone know how to resolve this . No problems with DIC preconditioner, and planning to work in 3D and believe this to significantly reduce computation time. Thanks for any insight or advice, Lori Holmes // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create mesh for time = 0 Reading field p Reading field U Reading/calculating face flux field phi Selecting viscoelastic model multiMode Selecting viscoelastic model Giesekus Starting time loop Courant Number mean: 0 max: 7.39649e-05 deltaT = 1.19999e-05 Time = 1.19999e-05 DILUPBiCG: Solving for Ux, Initial residual = 1, Final residual = 7.816e-11, No Iterations 2 DILUPBiCG: Solving for Uy, Initial residual = 0, Final residual = 0, No Iterations 0 Istream not OK for reading dictionary file: /home/pec/Desktop/solving_cases/giesekus_orig_GAMG/system/fvSolution::reconditioner at line 30.

Hi everone!
this problem seems to be persistent in foam-extend-4.0 still. Has anyone found a solution? Best regards, ma-tri-x |
