Thanx gschaider for the quick reply i found the solution to my problem

[khalid1059]

Thanx Bernhard Gschaider for quick reply. i got u and corrected this error. One more problem i m facing is now is that "when i uses foamMeshToFluent and foamDataToFluent then get .msh and .dat files. BUT WHEN I LOAD THESE FILES RESPECTIVELY IN FLUENT 6.3.26 I M NOT ABLE TO SEE RESULTS THOUGH THESE FILES HAVE BEEN SUCCESSFULLY LOADED " ALSO IN .MSH FILES obtained by foamMeshToFluent didnt include boundary conditions. i m transferring data for dieselFoam case.plz help me out

[khalid1059]

Hi hrv i m using dieselFoam tutorial on OF-1.5 and i wanna view the results on Fluent (I already have seen them on paraFoam)...now problem i m facing is that AFTER GETTING .msh and .dat files BY using foamMeshToFluent and foamDataToFluent WHEN I LOAD THESE FILES RESPECTIVELY IN FLUENT 6.3.26 I M NOT ABLE TO SEE RESULTS THOUGH THESE FILES HAVE BEEN SUCCESSFULLY LOADED. Whether additional parameters i must set to post process my case in fluent brfore loadinf it to Fluent?/?. I tried k epsilon model bedore loading .dat file on Fluent but still i didnt get results..Diesel Foam uses Euler Lagrange approach.... "

I ALSO noticd that in .MSH FILE obtained by foamMeshToFluent didnt include boundary conditions.I already have saved .msh file as .cas files but still no boundary conditions are set in (Define---->Boundary conditions).
i m doing MS process Engineering from islamabad and i am interested to post process OF results on different tools.....plz help me out

Hallo,

Importing results into Fluent seems to work fine but did anyone manage to do it in CFX-postproceossor?

So far I've managed to read in mesh in CFX-Pre but no success in CFX-post.

thanks,
Przemek

hello
Here I recently tried foamDataToFluent & foamMeshToFluent.But my fluent can not read them.It told me there is not a case file.
It didn't generate any case file.
Can you tell me why?
Thanks.

dear everyone..

i have followed the instructions given here for the viewing of an openfoam in fluent..

I have also saved the .msh file as case in my fluent and i have finally run my .dat file..

i have my whole system red colour in display->contour->velcity.

read_thread_data_section: invalid thread id 18.
Skipping data sub-section 2 for thread 1. Wrong size (3 != 2)
Skipping data sub-section 2 for thread 10. Wrong size (3 != 2)
read_thread_data_section: invalid thread id 11.
Skipping data sub-section 2 for thread 12. Wrong size (3 != 2)
read_thread_data_section: invalid thread id 13.

In my .dat case in fluent i notice the above.

2- why does i have a lot of .dat files? Am i not supposed to have found only 1?

i would be really grateful to anyone who answer my queries

regards
zaynah

Hi everyone,

i've tried to use the command "foamDataToFluent" as described in here, and i got ".dat" files for each time step of my simulation. Afterwards, i wanted to load the last step of ".dat" files to CFX5, but i got an warning message as follows:

" Note that for files other than CFX-Solver Results, global ranges are calculated for the used variables and the currently loaded timestep only. As more timesteps are loaded, global variable ranges are adjusted dynamically. Tip: To avoid dynamic range updates, you can use local variable ranges, or turn on pre-calculation of global ranges for all timesteps and all variables in : Edit>Options>CFD-Post>Files"

once i click on OK after this warning message, then i got the error message as follows :

"SEVERE
Operation failed. (System exception: Invalid fluent case file) "

So i am thinking of that the reason of this error message is the version i use in OpenFoam or in CFX. i am using OpenFOAM 2.1.x, and CFX14.0. so my question is, does anyone of you managed to do the conversion with those mentioned versions of O.F and CFX? or do you have any idea what the mistake may be?
thanks

Hello;

I am able to export the data (I use openFoam 2.2.0), but I cannot export just the last timeStep, it always transform every single timeStep.

OK, I could delete all the data I don't need, but the point is that it doesn't do what it is supposed to do... I have changed the ControldDict file, changing the startFrom to latestTime:

startFrom latestTime;
startTime 0;
stopAt endTime;
endTime 10000;
deltaT 1.0;
writeControl timeStep;
writeInterval 1000;
purgeWrite 0;
writeFormat ascii;
writePrecision 10;
writeCompression uncompressed;
timeFormat general;
timePrecision 6;
graphFormat raw;
runTimeModifiable true;

I have tried also setting the startTime to 10000, but it anyway exported every timestep.

Any clue??

Thank you very much!

Hi Dogan,

Did you manage to solve the problem? I could open my .cas and .dat in Fluent but I am facing the same problems that you wrote.

Please advise. Many thanks.

Best regards,

Hello dogan,
have you finally found an answer to your question? I am facing the same problem, I'm trying to import .dat in CFD-Post (CFX post-processor) without positive results. I get the same error you reported...I can successfully import the mesh but just the mesh without scalars...

Any suggestion?

Hi all,

I have (as far as I can tell) successfully used the foamMeshToFluent and foamDataToFluent command. More precisely I made my mesh in Ansys Mesh Modeler and saved it in ASCII format and successfully imported it to OpenFOAM (with the fluentMeshToFoam utility). This is what I have done step by step:

-Model mesh in Ansys mesh modeller, save in ASCII format.
-Import mesh in OpenFOAM (fluentMeshToFoam utility).
-Performed a seemingly successful K-Epsilon RNG simulation within the HelyxOS environment.
-Checked results in paraView (Looks pretty realistic).

Now I want to post-process my results on Win7 with Ansys CFD Post or Fluent (since that utility is available). Here is what I have tried so far:

-Export the .dat file with foamDataToFluent and exported the mesh with foamMeshToFluent to get the .msh mesh file.

Opening the .msh file in Fluent(Win7, different machine) works, I can see the mesh and it looks fine. All faces (inlet, outlet, symmetry) are defined and I set Fluent to K-Epsilon RNG so it has the correct variables available. Now when I try to import the .dat file Fluent gives the follow error:

''Warning: case and data files are inconsistent zone 10[xxxx,xxxx] data [xxxx,xxxxx]"

This error is repeated for all zones in the mesh.

Hope you guys can help! Thanks in Advance,

Joris

Dear Robinp, I'm also using XiFoam and would like to convert the results to Fluent. My problem is that if I only convert the T,U,P there is no problem but when I add one species, the fluent will have problem in reading the .dat file. Do your have any idea on this problem? Thank you!

[masoudsh]

Hi Joris

I have your problem too.
do you solve it?
please someone help me.

hi Foamers

I am using foamDataToFluent for postProcessing. It works well and the last few message from terminal I can show as:

Time = 98
Converting field p
Converting field T
Converting field U

Time = 99
Converting field p
Converting field T
Converting field U

Time = 100
Converting field p
Converting field T
Converting field U

End

But when I load this data file in Fluent I can't get contour of temperature nor the wall heat flux. What could be the possible reason!!!

Hi foamers,

It is an old thread but I have the same problems as you.

I did the mesh and simulation and I would like to openthe mesh and data in CFD-Post. I did the foamMeshToFluent and foamDataToFluent .. I can see the mesh in CFX Post but I was not able to import the data results

I saved the .cas with the .msh but still unable to import the data results. Could be worng the name of the files with the time? Any guess?

Thanks,
