Sorry, I don't have enough time for everything .

Read the cfMesh manual. It's very easy to use.
Thanks, Bruno. I have another question. I would like to implement the following boundary condition on the wall of my domain.

Gradient(Phi) = sigma/A; where sigma is varying along the axial direction and A is constant. How do I incorporate this non-uniform boundary condition. I know how to implement the BC if sigma is a constant.
Can you throw some light on this.

Thanks

Regards,
Vishal

Quick answer: GroovyBC might be the easiest way to implement that: http://openfoamwiki.net/index.php/Contrib/groovyBC
