How to use faceList instead of faceCompactList

Hi!

The new snappyHexMesh includes feature edge handling which may significantly improve the quality of your mesh.
http://www.openfoam.com/news/snappyH...ature-edge.php
Now my problem is that I need to perform my calculations on an older OpenFoam-Version 1.7.1 where this feature is not supported, yet. So I tried to create the mesh with version 2.0.0 and then use the mesh in Version 1.7.1. Unfortunately the new version 2.0.0 stores faces in a compact list "faceCompactList" which is not recognized in 1.7.1 where only "faceList" is known.

So my question is:

Does anybody know, how to deactivate the usage of faceCompactList and use faceList instead, so I can use the mesh in the older version 1.7.1???
Or maybe you have another idea to overcome this problem....

Thanks a lot

BTom

utility to convert from compactFaceList to faceList

It is easy to write the code, see the attached, if you havn't done this already

Hello! I'm very new to foam-extended. I'm trying to work there with a mesh I did in OpenFOAM v8. I see the .tar folder but I'm not sure how to use it, how to set it up in foam-extend 4.0 to get the utility to work.

Any help would be appreciated.

Make sure your OpenFOAM environment variables are set. Download the tar.gz file and copy it to $WM_PROJECT_USER_DIR. Untar the file and edit Make/files, changing

Code:

EXE = $(I_DIR)/bin/compactFaceToFace

Code:

EXE = $(FOAM_USER_APPBIN)/compactFaceToFace

Run wmake in the compactFaceToFace folder. It may be necessary to add additional libraries to the Make/options file. In my case it was.

Code:

EXE_INC = \

    -I$(LIB_SRC)/finiteVolume/lnInclude \

    -I$(LIB_SRC)/meshTools/lnInclude



EXE_LIBS = \

    -lfiniteVolume \

    -lmeshTools

After compilation, you should be able to run the app compactFaceToFace from within the desired case directory.

Hi, I have the same problem on foam-extend 4.1 e solids4Foam 2.0. When I go to run make I get these errors and it doesn't compile. Can you help me?
