Thank you.
Couple of more questions:
1. You have p and u variables in your equation. Is this a misprint?
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 ?
3. Where cam I read about the Newmark method of solution, that you have
implemented?
Thank you again,
Michael.

Dear Libmesh developers,
could you, please, tell which equation is solved in the example
transient_ex2.C?
Looks like some kind of second-order wave equation to me,
(1/c^2) d^2 p / dt^2 - Laplacian(u) = 0
but you should double check the signs that are used by the
NewmarkSystem internally...
