Hi all, I ran a steady stat
 

Hi all,

I ran a steady state case with simpleFoam and converted the mesh/solutions to fluent format using foamMeshToFluent and foamDataToFluent.

Relevant part of my foamDataToFluent file:
p 1;
U 2;
k 5;
omega 63;

But when I ran fluent 3d and loaded the .msh and .dat files, I could not plot k and omega. For some reasons, the viscous model is set to laminar.

Anyone ran into this issue before? Thx in advance.

I found the reason -- forgot t
 

I found the reason -- forgot to set the turbulence model BEFORE I loaded the data. Now they plot fine.

However, when I choose report forces, I get zero viscous forces... do I need some specific quantities for fluent to calculate the viscous forces?

If so, how do I get those to be output in OpenFOAM?

Thx again,
Ned

Ned,

As a newbie with openFOAm can you guide me as to where to get a list of the Unit Numbers (for p U k omega etc) we need for the conversion of data to fluent.

They should be in $WM_PROJE
 

They should be in

$WM_PROJECT_DIR/applications/utilities/postProcessing/dataConversion/foamDataToF luent/fluentUnitNumbers.txt

hi forum,

I am struggling to convert the reynold's stress form openFoam to Fluent, can anyone please help me ???
This is what I am writing in the foamDataToFluentDict, but in the command prompt it shows converting U, p, epsilon and k but nothing like Rxx, Ryy..etc.
Rxx 128;
Ryy 129;
Rzz 130;
Rxy 131;
Ryz 132;
Rxz 133;

Thanks,
Mahendra.

I think FoamData to Fluent conversions are not as accurate.

When i converted data of my simulations from foam to fluent, i got very absurd results.

All th inlet and outlets were set to pressure outlets also at boundary i had given Y veloity to be 0.5 m/sec in fluent it showed 0.2 m/sec.

If somebody has experienced similar problem plz let me kno how have you solved it.

@ ameya

I experience the same problem. foamData/MeshToFluent doesn't convert the BC's. This seems to give the wrong values at patches. I tried to calculate the flow through a simple tube and found the mass balance being about 10% wrong while comparing two surfaces near the inlet/outlet was fine.

So the conversion is accurate but incomlete.
I'm not sure if there's an option to copy also the boundaries, otherwise I'd have to write one myself.

Results doesn't fit when transforming data to Fluent
 

Hello;

I have run a case in OpenFoam and exported the data to Fluent.

I think that I have done every step correctly, but the results doesn't fit -(0 0 0) viscous force???!!!!- :

The values of the velocity doesn't completely fit, not even between in the calculations done with OpenFoam and Fluent (see attachments).

I have read that the data transfer from OpenFoam to Fluent is not actually working.

Is that true? or there is something to do and fix it somehow???

Thank you!
