Hi again Dragos!

I probe with laplacianFoam solver, and my program run, but when I see the results in paraview, nothing change... the temperature behavior is always the same, don't change with time...

I review all, and I don't know what's wrong...

If you have an idea of which can be my mistake, i will be grateful.

If you start from a constant temperature field and the same value for the boundaries, then nothing should change, but this is just a guess since I don't know your settings.
What is your initial field and what are the values at the boundaries?

The inside of the sphere is a 1000 and the surface a 100. With this values, the sphere should be colder... but nothing happen.... Ah! my DT=1.477E-5.
