Problems after converting a CCM Model
 

Hello everyone,

I'm studying aerospace engineering at the Technical University of Munich. I have just begun working with OpenFOAM, so I'm still a rookie with the software.

Right now, I have completed all the tutorials and exercises and I would like to start s small own example, but I have several questions.

What exactly is FoamX? I haven't found any specific information neither in the User's Guide nor in the Programmer's Guide. Could you please help me with this problem? Moreover, where can I download the programm, or is it already included in the standard OpenFOAM 1.6 installation?

Are there any ohter methods to integrate the boundary conditions? I have converted a CCM Model with ccm26ToFoam, but now I have trouble with the definitions of the blockMeshDict. How can I automatically define the vertices, without having to name every each of them? Shouldn't they already be made by ccm26ToFoam?

Thanks for your held, I might need some more help for the general understandig of OpenFOAM's behaviour ;)

Greetings,
Erik

If you have converted a ccm+ mesh to foam, then you don't need the blockMeshDict file. This is for the block-structured mesher that comes with foam called blockMesh. If you have named your boundaries properly in ccm+ before converting it, then you should have a list of your boundaries in the <casedir>/constant/polyMesh/boundary file. You specify the specific boundary conditions to apply at each of these boundary zones listed in <casedir>/0 directory, like in the other tutorials.

Does that help at all?

Hi madad2005,
thank you for your help, yes it helps! I deleted all old files in the case, reconverted the .ccm-file and now worked fine.

Now I can see the mesh in ParaView. But the problem is, when I want to apply "p" to the mesh in ParaView, the programm crashes. Here's the error message:
__________________________________________________

I don't know why "ground" should be undefined in p
Here's the "p" file:

Actually, there's no keyword ground at all?!

I've got a feeling you can't use the underscore ('_') when defining patches. Change it to a '-' and it should work.

I did as you said. I even tried different combinations, like deleting all "_" or "-" or replacing the "2" by an "a".
The Mesh in ParaView is fine, an I even see the different nominations in the"Mesh Parts", but when I like to apply either "p" or "U" it crashes, with followiong statement:

Any ideas?

What are you running that gives you this error message (by far the biggest I've ever come across, but I'm not big expert)? I see some vtk-related libraries being called, which is strange unless you are trying to convert foam data to vtk format?

Are you trying to run this mesh with a solver or just visualise it? Can you post the output of checkMesh? Also, as a side note, run renumberMesh and then do what you did before to see if you get the same issue.

It should just be a test case to see how the CCM converter works, I haven't applied any solver yet, nor did I any vtk related operations - voluntarily ;-)

This is the checkMesh result:

Could it be, that I need to specify "p" an "U"? But I actually have them specified in "0". Do I need to copy the hole case into a solver sub-directory? It is now in my "run" directory on the same level as the "tutorial" are.

Can you paste your p and U files so I can have a look?

Sure!

Here's p:

Why have you set left and right to type wall? I don't think you can do that in the 0/ dictionaries, as that word can only be used in your boundary file (someone correct me if I'm wrong). The correct pressure boundary condition type for an external flow is normally zeroGradient. Also, as far as I'm aware the empty type is required for the parallel faces in 2D meshes. Now, I'm not too sure whether these are the specific errors from which your errors are arising, but best to fix them and then try again.

What are you trying to model?

Btw, FoamX is no longer supported and it wasn't that good anyway (imo).

Hi madad2005,

thank you for your help, I've managed to get the case running. The problem were some wrong initial conditions for p and U. Now the conversion and the processor are both running. I appreciate your help!
