Salome Geometry
" Simple geometry:
" Set units
" Create geometry
" Create Groups from geometry elements  names will be seen in the
OpenFoam settings
Example
" Simple geometry
" Cavity
" Channel
" Sphere
" Complex geometries:
" Cut geometries
" Translate
Salome Mesh
" Meshing:
" Create mesh
" Compute mesh
" Create Groups from Geometry
" Export mesh as UNV
Example
" Simple geometry
" Hexa mesh
" Tetra mesh
" Complex geometry
" Size of the mesh
Python
" When finished creating Geometry and Mesh create Python script
" File  Dump Study
" Python script will be created in the working directory
" Modify script
" Import back to the Salome
" File  Load Script
" Run Salome in the background:
" Open terminal window
" Type:  salome  t script.pt
" Files with geometry and mesh will be created in the working directory
Import Mesh to OpenFoam
" Place file .unv with geometry and mesh in the case folder
" Open terminal window
" Type:  ideasUnvToFoam fileName.unv
" Check folder constant  polyMesh  boundary
" Check folder  0 if the same names of boundary conditions are
defined

tetgenToFoam Converts .ele and .node and .face files, written by tetgen
vtkUnstructuredToFoam Converts ascii .vtk (legacy format) file generated by vtk/paraview
writeMeshObj For mesh debugging: writes mesh as three separate OBJ files which can be viewed with e.g. javaview
Case Setup
" Create case FOLDER
" Create subfolder  0 ,  constant ,  system (copy tutorials and make
new simulations based on predefined case)
" Place mesh in the case folder
" Run application to  translate geoemtry to OF polyMesh folder
" Check/Change boundary condition names in polyMech  boundary
file and in  0 folder. Names should be the same in  boundary and in
 0 folder.
Case manipulations
" All scripts are in  system folder
" setFields
" refineMesh
" decomposePar
Case constants
" To change specific variables related to case setup go to  constant
folder.
" Each case will be different. Everything depends on the main goal of
the simulations
