foamToVTK ERROR
Hi at all!
I've done a simulation with reactingFoam. Now I've a folder for every writing point that is fixed in the controlDict file. The next step is postprocess the case with paraFoam but I'm working in a parallel environment and there is only paraview installed. So I thought to use the foamToVTK utility to visualize the case with paraview. When I run this utility this error encountered: --> FOAM FATAL ERROR: More than one patch accessing the same transform but not of the same sign. patch:CameraFL1_shadow transform:0 sign:-1 current transforms ( -1 0 0) From function Foam::label Foam::globalIndexAndTransform::addToTransformIndex ( const label, const label, const bool ) const in file lnInclude/globalIndexAndTransformI.H at line 240. FOAM exiting I've done the mesh in gambit ad I've exported it with fluent3DMeshToFoam utility. The mesh has some surfaces defined as cyclic, CameraFL1_shadow is one of this. Someone know how this error encountered? Thanks a lot. |
Greetings Bombolati,
I'm not sure at which level you're doing parallel processing, but if in the cluster you can load the whole case in a single machine for post-processing, then you could use ParaView's internal ".foam" reader. Run this command inside your case folder: Code:
touch case.foam As for the problem with foamToVTK: did you check the mesh before running the case? Code:
checkMesh -constant Bruno |
Hi Bruno and thanks a lot for you answer. I used the first command to create the file <<case.foam>> and all is ok. Next I tried to use the utility <<check mesh>> and some problems come out. I post here below the result:

Hi Bombolati,

You'll find a usage example for fluent3DMeshToFoam: http://openfoamwiki.net/index.php/Fl...y_step_example As you can see, in that example it also indicates that you should check the mesh after conversion ;) I'm not familiar with fluent3DMeshToFoam, so my advice is to look in the forum for the keywords: Code:
fluent3DMeshToFoam cyclic Best regards, Bruno |
