Adaptation to OpenFOAM 2.1.x of "Christoffer Järpner: Projection of a mesh on an stl surface" available at http://www.tfd.chalmers.se/~hani/kurser/OS_CFD_2011/ which originally was for OpenFOAM 1.6-ext.

Description

Brought to my attention here: http://www.cfd-online.com/Forums/openfoam/105558-need-directtopochange-h.html

Source of modifications at http://www.tfd.chalmers.se/~hani/kurser/OS_CFD_2011/:

Original sources from OpenFOAM 2.1.x and 1.6-ext:
  • 2.1.x commit 334ec14f742f95b1198bc0de318d625fc724b5e7
  • 1.6-ext commit c04489736fa1e44c123c6d801f54044f2679bfca
This git repository was brought to you by Bruno Santos (wyldckat@github working at blueCAPE Lda).

Usage instructions

  1. Download, either using git or use the Downloads pseudo-button on the top right at https://github.com/wyldckat/CJsnappyHexMesh.
  2. Depending on whether you're using 1.6-ext or 2.1.x, go into the respective CJsnappyHexMesh* folder.
  3. Run: 
    wmake
  4. Go to the respective case folder tutorials/SnappyTestCase-* and there you can run one of the following 2 commands: 
    ./Allrun
./Allrun2
  5. Read the comments in Allrun2 to learn the differences between the two scripts.
  6. Reset the case folder by running: 
    ./Allclean

Additional adaptations

Given that Christoffer Järpner's modifications were meant for 1.6-ext, there were several adaptations required for things to work with 2.1.x. Those were:

  1. Had to include: 
    #include "polyTopoChange.H"
#include "polyTopoChanger.H"
    Instead of: 
    #include "directTopoChange.H"
  2. This lead to renaming the references of directTopoChange to polyTopoChange.
  3. Added references to dynamicFvMesh in Make/options.
  4. This: 
    boolList boundaryPoint(mesh.allPoints().size(), false);
    Changed to this: 
    boolList boundaryPoint(mesh.points().size(), false);
  5. Had to stich by hand some of the modifications to mysnappyHexMesh.C.

Whenever there was a problem during the build, I looked for the variable/class/name in 1.6-ext's folder applications/utilities using grep. Example: 

grep -r "directTopoChange.H" *
Then looked at grep's output, picked out a file where the occurence was found and opened the respective file in 2.1.x. Compared the differences and voilà!
