Tags internal faces, openfoam, pre processing

Objective: test cases for using following dicts:

createPatchDict
createBafflesDict

Preliminary steps:

Run the Salome script for the geometry and surface mesh generation
Export walls, inlet outlet inside cad/stl as STL (ASCII)
Run the utility buildRegionSTL, it will create the constant/triSurface folder with buildRegionSTL.stl
Export the interna mesh as interna.stl inside constant/triSurface

************Set up the SHM dict file for create Patch (highlights)...

Following code has to be copied into your ./bashrc on linux system to merge toghether several STL files saved into cad/stl folder.

For more details, have a look to this screen cast

thanks Tobi

Code:

function buildRegionSTL() {
    if [ -d "cad/stl" ]

fms file creation

Code:

surfaceToFMS file.stl

extraction of edges from stl file

Code:

surfaceFeatureEdges file.stl file.fms -angle 30

This is to visualize with paraview

Code:

FMSToSurface -exportFeatureEdges file.fms fileEdge.fms

#several steps for improving mesh quality

Code:

cartesianMesh.exe
checkMesh.exe >> log.Mesh1
improveMeshQuality.exe
checkMesh.exe >> log.Mesh1
improveMeshQuality.exe
checkMesh.exe >> log.Mesh1
improveSymmetryPlanes.exe
