Hi Foamers,
I am new to OpenFOAM and I need to write a diffusion equation , I have read the examples and I can't identify my case d[ nu (dT/dx) ] /dx + d[ nu (dT/dy) ] /dy + d[ nu (dT/dz) ] /dz = 0 ; nu and T are scalar Fields , nu can be a constant to Thanks for your help Jimmy |

This is written as:
Code:
fvm::laplacian(nu,T) Take a look at laplacianFoam, this solver solves the diffusion equation. |
