libOpenSMOKE - Making it work once again with OpenFOAM

The other day Tobi asked for my help on building http://www.cfd-online.com/Forums/ope...opensmoke.html
After looking at the code and doing some trial and error, basing myself also on Tobi's already collected information, I managed to get it built/working with OpenFOAM 1.7.x, 2.0.x and 2.1.x.

And since the original page only provided a rarball (on Linux?) of the source code, I decided to use my github account to harbor the original code along...

codedFixedValue Boundary Condition

Posted April 11, 2012 at 17:57 by Hisham (Notes for OpenFOAM!)

Tags boundary, codedfixedvalue, openfoam

This is an example of using codedFixedValue boundary condition to input expressions that are time and position dependent.

Code:

    PatchName
    {
      type               codedFixedValue; 
      value              uniform (0 0 0); //$internalField;
      redirectType    BC_Given_Name; 
      code 
	#{ 
	     fixedValueFvPatchVectorField myPatch (*this);
	     forAll(myPatch, celli)
	       {
	         myPatch[celli]

Cyclic (Periodic) Boundary Condition

Posted April 11, 2012 at 17:57 by Hisham (Notes for OpenFOAM!)
Updated April 12, 2012 at 07:12 by Hisham

OF V.2.x
Cyclic (periodic) boundary condition is used to model repetitive geometries by joining two patches as if they were physically attached to each other!
The "simplest" way to apply a cyclic BC is to have two patches that are identical and define them in the ./constant/polyMesh/boundary as:

Code:

 RightPatch
    {
        type            cyclic;
        nFaces          49;
        startFace       9506;
        neighbourPatch

Using a hybrid mesh for a simple pipe

Posted February 23, 2012 at 22:18 by rikio

The method to create a hybrid mesh.

You can check the help from there to get the rest of the way.
