Hi,

your OpenFOAM installation seems to be correct, the command has been found and run. You need to tell the program surfaceCheck the surface file that needs to be checked.

For example (using a *.stl file containing a surface triangulation):

Code:

surfaceCheck yourSurfaceFile.stl

You can always get infos on how to run a command using the -help command line argument (surfaceCheck -help in your case).

thank u Cutter, that was the Problem.

an now after im running surfaceCheck name.stl vor example the Inlet, becouse i split my geometry wenn i export as stl. , and my inlet is like an quader in the middle of a face. so its comes this information:
thats mean the stl file is not correkt?

No problem!

Please copy&paste the command's whole output next time! The command ran successfully, but your surface is not-closed.

I can only guess without knowing your intentions, your geometry and the whole surfaceCheck output, but I think you split your geometry in separate patch files and check only a single one of them. This single patch is of course not closed (no manifold or '"water tight" surface), which might be ok depending on your workflow. In order to obtain a complete closed surface mesh you might want to concatenate the patch files into one big geometry file containing all the patches. This can by assigning proper names in the headers of the *.stl files and using the cat command to write them into a single file.

Please have a look at http://www.cfd-online.com/Forums/ope...-addition.html, steps 5&6!
