Hi,

I am having problems with the shockTube tutorial.

I just entered the corresponding shockTube folder, created the mesh with "blockMesh" and entered the command line "rhoCentralFoam" and then the terminal showed the following error messages:

--> FOAM Warning :
From function polyBoundaryMesh::groupPatchIDs() const
in file meshes/polyMesh/polyBoundaryMesh/polyBoundaryMesh.C at line 474
Patch empty specifies a group empty which is also a patch name. This might give problems later on.

I do not understand what happened to this tutorial?

Could somebody help me?

Hi, have you execute the "setFields" command before the "rhoCentralFoam" ?

Oh, I forgot "setfields"! Thanks!
