foamDataToFluent
 
hello
I need to export OpenFoam 220 data to fluent for plotting axial velocity contours which I can't plot them with Paraview and I followed this instruction

http://www.cfd-online.com/OpenFOAM_D...es/1/1212.html

but It didn't solve my problem and I got this error ::confused:

--> FOAM FATAL IO ERROR:
cannot open file

file: /home/ali/OpenFOAM/ali-2.2.0/run/tutorials/incompressible/icoFoam/u/system/foamDataToFluentDict at line 0.

From function regIOobject::readStream()
in file db/regIOobject/regIOobjectRead.C at line 87.

I would be so appreciate if someone give me detailed instruction .
thanks

In /OpenFOAM-2.2.2/applications/utilities/postProcessing/dataConversion/foamDataToFluent you can find an exampe (which you have to copy into your case's system directory:

I got it .thanks.
It was really helpful but (.cas) file was not made and I just have (.dat) files for each time step so fluent can't open it and give me an error that (.cas) file in necessary.

If I remember correctly, the .cas file contains the mesh. You can create it with foamMeshToFluent.

Hi

I use foamDataToFluent and I get the uotput results in openfoam with Suffix .dat
then I bring it to CFD post but encounter to this problem :

cannot get mesh information.look likes mesh file is missing

I don't know how add mesh file to CFD post.
It's enough to put polymesh in folder that .dat existence

thanks
Masoud
