Hi all,

I try to learn OF, but I don't get a clue how to use the mergeMeshes - command.
What I want to learn: I've got two meshes from FLuent a rotor and stator. Now, I would like to join them and try to make a MRF.
First I've translated them in different folders (rotor / stator, structures according to OF) and made fluentMeshToFoam. That was ok, but how can I merge them in one central folder, now?

If I try to run the tutorial for turbomachines (http://openfoamwiki.net/index.php/Si...vaned_diffuser)

All the time I get a failure: Cannot find file "points" in directory "constant/polyMesh"

So, can someone help me how to build and setup an rotor/stator-mesh in foam ?

Thanks in advance.

Hi,
I do not quite understand the Centrifugal Pump either but I can help you with your problem.

First of all I suggest you put the converged meshes in two different folders with are set up like a normal case. OpenFOAM always complains when when some file like the controlDict is missing so I always copy the structure from an other case to shut OpenFOAM up.
So if you got the two meshes in different casefolders with different casenames you are ready to go. Lets say the two cases are in "../run/blabla1" and in "../run/blabla2" and the casenames are "rotor" and "stator" this is what you need to execute:

mergeMeshes <master root> <master case> <root to add> <case to add>

In your case that would mean you have to type in this:

mergeMeshes "../run/blabla1" rotor "../run/blabla2" stator

That way you creat a new timestep in the ../run/blabla11/rotor folder.
Check it out thats where you find your new merged mesh.
