Template case files to help general setup of OpenFOAM cases

Browse Source 
The templates include a stategy to simplify meshing with snappyHexMesh,
particularly to help generate an initial mesh quickly that can subsequently be
improved.  The templates are setup to enable rapid initial simulations, typically
with simpleFoam.  The initial templates cover simple inflow-outflow and closed
domains, including rotating geometry, and an example axisymmetric flow.  For
more details, consult the README file accompanying each template case.
The cases are located in $FOAM_ETC/templates

Overview
=======
+ This is a template case for a closed volume
+ Setup to run buoyantBoussinesqSimpleFoam
+ The case is designed to be meshed with snappyHexMesh
+ snappyHexMesh is setup to use a single trisurface file named CAD.obj
+ Copy the CAD.obj file to the constant/triSurface directory
+ The CAD.obj can contain one or more regions to create patches in the mesh
+ The user can then specify different boundary condition on T on these patches
Meshing
=======
+ Meshing is setup as in the inflowOutflow template
+ See $FOAM_ETC/templates/inflowOutflow/README for details
+ The setup includes an example for one named patch to be generated in the mesh
+ In snappyHexMeshDict, replace <CADregionName> with the name of region in the
trisurface; replace <patchName> with the name of the resulting mesh patch
Initialisation
==============
+ In the field files in the 0 directory, set initial values
+ The template includes a fixedValue boundary condition on <patchName> in 0/T
+ The user can replace <patchName> with a real mesh patch name and apply a
fixed temperature on that patch
