In release notes for 1.3，
it talked about there are several newpost-processing utilities added--including

"polyDualMesh"
(converts polyMesh into its vertex-based dual mesh)"

I try to know how to use this,but there are no information about its usage.

Do someone know how to use,or have a example case about that?

thank you very much! http://www.cfd-online.com/OpenFOAM_D...part/happy.gif

Take a mesh (e.g. lid-driven cavity tutorial) and run polyDualMesh. It will write a new mesh in a time directory (0.0005?). Move this polyMesh directory to the constant directory.

It will run on any OpenFOAM mesh. Quite funny on tet meshes.

And the name of this time directory is decided by "deltaT" in controlDict.
If we set deltaT=100,it will write new mesh to (case)/100/polymesh .

Is there other command to run
 

Is there other command to run analysis for "node based" mesh?

now I have a dual mesh,but the results looks not having difference with orignal mesh.
