Hi there,
I am not new to openFOAM, but I used OF 3 years ago, now I am doing a project in OF.
my question is very simple.
I have created mesh in fluent (.msh), now I need to convert in to OF.
my question is,
1) what are the folders and files should be in my case folder?

I have done something as follows,
* created case folder called Test
* copied 0 constant and system folders in to my case folder
* copied my .msh file in to Test/constant/polyMesh$
* I tried Test/constant/polyMesh$ fluentMeshToFoam fluent.msh
I am getting fatal error

can any one help me to over come this issue
please give me the steps, which i should follow

thanks,

Greetings sivakumar,

When in doubt:

Check tutorials that OpenFOAM has:
Code:
```
find $FOAM_TUTORIALS -name "*.msh"
```
Or ask help directly :
Code:
```
fluentMeshToFoam -help
```

In your case:

cd to Test

Code:

fluentMeshToFoam constant/polyMesh/fluent.msh

In some cases, use fluent3DMeshToFoam instead.

Best regards,
Bruno
