Dear Christophe,
I am a new user of GetDP, and I need to compute the propagation of an
acoustic wave inside a horn (with a non constant cross section along the
propagation axis).
The equation looks like this:
d²P dP d(ln(S))
----- - ----- * ----------- + k²*P = f
dx² dx dx
With mixed Derichlet and Neumann boundary conditions (Robin BC).
Please could you show me how can I write this in the right procedure ?
Thank's a lot for your help
