Hello Foamers,
Good day! I am a beginner to OpenFOAM, currently, I am using 'ofv40' and trying to run a custom solver regarding the modeling of water transport in PEMFC. After creating mesh by using 'blockMesh' I tried to run the custom solver and got this error: --> FOAM FATAL ERROR: Cannot find file "points" in directory "abp/polyMesh" in times 0 down to constant From function Foam::word Foam::Time::findInstance(const Foam::fileName&, const Foam::word&, Foam::IOobject::readOption, const Foam::word&) const in file db/Time/findInstance.C at line 182. FOAM exiting Any idea how to solve this issue? Thanks in advance. |

where is your polyMesh-directory?

yeah thats the problem
normally, it should be in the constant-directory, once blockMesh is executed. what is the terminal output when you execute blockMesh? |

thats a strange behaviour.
we will need to do further investigation. what is the solver you created? did you modify an existing solver? if yes, where did you do the mod? if no, how did you create the new solver? |

Well, it's a custom "PEMFC Single-Phase Non-Iso thermal model" solver tool, I found it online which is well suited to my interests. However, I think there is something wrong with the already constructed geometry.

I had the same error while using reconstrucPar. In my case, a multiregion mesh, I solved it by adding the option -allRegions

Hi all, I want to study the flow in a tube, inside the tube is a propeller. When I run the case, it appears the following fatal error
--> FOAM FATAL ERROR: Unable to find cellZone innerCylinderSmall. Valid cellZones are:1(rotor) From function Foam::solidBodyMotionSolver::solidBodyMotionSolver (const Foam:olyMesh&, const Foam::IOdictionary&) in file motionSolvers/displacement/solidBody/solidBodyMotionSolver.C at line 85. FOAM exiting Is there any idea, how to solve this problem. Thank you in advance. |

It is pretty much what the error message tells:
In polymesh/cellzones you only have one zone defined (rotor) but in one dictionary you want to access a zone which is not defined (innercylindersmall) So you need to correct the naming |

Dear geth03,
Thank you for your answer. Following your instructions I tried to define the zone in dictionary cellzones, but it has this form when I opened it. Please inform me why the dictionary looks. /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: v1812 | | \\ / A nd | Web: www.OpenFOAM.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format binary; class regIOobject; arch "LSB;label=32;scalar=64"; location "constant/polyMesh"; object cellZones; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // 1 ( rotor { type cellZone; cellLabels List<label> 2619 (;!\00\00<!\00\00=!\00\00>!\00\00?!\00\00@!\00\00A !\00\00B!\00\00C!\00\00D!\00\00E!\00\00F!\00\00G!\ 00\00H!\00\00I!\00\00J!\00\00K!\00\00L!\00\00M!\00 \00N!\00\00O!\00\00P!\00\00Q!\00\00R!\00\00S!\00\0 0T!\00\00U!\00\00V!\00\00W!\00\00X!\00\00Y!\00\00Z !\00\00[!\00\00\!\00\00]!\00\00^!\00\00_!\00\00`!\00\00a!\00\00b!\00\00c!\ 00\00d!\00\00e!\00\00f!\00\00g!\00\00h!\00\00i!\00 \00j!\00\00k!\00\00l!\00\00m!\00\00n!\00\00o!\00\0 0p!\00\00q!\00\00r!\00\00s!\00\00t!\00\00u!\00\00v !\00\00w!\00\00x!\00\00y!\00\00z!\00\00{!\00\00|!\ 00\00}!\00\00~!\00\00!\00\00\80!\00\00\81!\00\00\ 82!\00\00\83!\00\00\84!\00\00\85!\00\00\86!\00\00\ 87!\00\00\88!\00\00\89!\00\00\8A!\00\00\8B!\00\00\ 8C!\00\00\8D!\00\00\8E!\00\00\8F!\00\00\90!\00\00\ 91!\00\00\92!\00\00\93!\00\00\94!\00\00\95!\00\00\ 96!\00\00\97!\00\00\98!\00\00\99!\00\00\9A!\00\00\ 9B!\00\00\9C!\00\00\9D!\00\00\9E!\00\00\9F!\00\00\ A0!\00\00\A1!\00\00\A2!\00\00\A3!\00\00\A4!\00\00\ A5!\00\00\A6!\00\00\A7!\00\00\A8!\00\00\A9!\00\00\ AA!\00\00\AB!\00\00\AC!\00\00\AD!\00\00\AE!\00\00\ AF!\00\00\B0!\00\00\B1!\00\00\B2!\00\00\B3!\00\00\ B4!\00\00\B5!\00\00\B6!\00\00\B7!\00\00\B8!\00\00\ B9!\00\00\BA!\00\00\BB!\00\00\BC!\00\00\BD!\00\00\ BE!\00\00\BF!\00\00\C0!\00\00\C1!\00\00\C2!\00\00\ C3!\00\00\C4!\00\00\C5!\00\00\C6!\00\00\C7!\00\00\ C8!\00\00\C9!\00\00\CA!\00\00\CB!\00\00\CC!\00\00\ CD!\00\00\CE!\00\00\CF!\00\00\D0!\00\00\D1!\00\00\ D2!\00\00\D3!\00\00\D4!\00\00\D5!\00\00\D6!\00\00\ D7!\00\00\D8!\00\00\D9!\00\00\DA!\00\00\DB!\00\00\ DC!\00\00\DD!\00\00\DE!\00\00\DF!\00\00\E0!\00\00\ E1!\00\00\E2!\00\00\E3!\00\00\E4!\00\00\E5!\00\00\ E6!\00\00\E7!\00\00\E8!\00\00\E9!\00\00\EA!\00\00\ EB!\00\00\EC!\00\00\ED!\00\00\EE!\00\00\EF!\00\00\ F0!\00\00\F1!\00\00\F2!\00\00\F3!\00\00\F4!\00\00\ F5!\00\00\F6!\00\00\F7!\00\00\F8!\00\00\F9!\00\00\ FA!\00\00\FB!\00\00\FC!\00\00\FD!\00\00\FE!\00\00\ FF!\00\00\00"\00\00"\00\00"\00\00"\00\00"\00\0 0"\00\00"\00\00"\00\00"\00\00 "\00\00 "\00\00"\00\00"\00\00 "\00\00"\00\00"\00\00"\00\00"\00\00"\00\00"\ 00\00"\00\00"\00\00"\00\00"\00\00"\00\00"\00 \00"\00\00"\00\00"\00\00"\00\00"\00\00"\00\0 0 "\00\00!"\00\00""\00\00#"\00\00$"\00\00%"\00\00&"\ 00\00'"\00\00("\00\00)"\00\00*"\00\00+"\00\00,"\00 \00-"\00\00." |

Hello Konstantinos,
You cannot directly edit the cellZones file, you have to create it when creating your mesh (for instance in snappyHexMeshDict) or use topoSet to create it afterward. Regards, Yann |

Details: ->reconstructPar giving Fatal error for cannot find "Point" file in directory "Polymesh" ->try select "decomposed case in paraview" and failed with errors showing " ...faces.gz cannot open..." ->check processor directories and found "constant" folders in proccessor* folders disppear after parallel running. ->run reconstructPar -allRegions and fixed Also some other threads had suggested to copy the case and do decomposePar again, then copy constant files back to the processor* directories of the original complete case. However this would too much trouble for my 40 cores case. |
