Thank you, Roy. One more question, please. How can I get dp/dt, if I need? Is there an existing solution for this? Thank you!

Couple of more questions: 1. You have p and u variables in your equation. Is this a misprint? Yes, sorry there is only one variable, p. 2. It seems there is also a force term. In the example you integrate it over a surface. Can I have a volume force, to solve something like this: (1/c^2) d^2 p / dt^2 - Laplacian(p) + F = 0 ? Sounds reasonable to me. 3. Where cam I read about the Newmark method of solution, that you have implemented? I would assume it something similar to this: https://en.wikipedia.org/wiki/Newmark-beta_method but of course looking at the code to see what it does is your best bet... -- John _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
