Hi what would be the best way of solving a second order linear partial
differential equation in time of the type in LibMesh:
[M] d^2u/dt^2 = [K] u + [F]
I could obviously break it down into sets of equations - one solving for the
first derivative and other for u itself but I'd like to know if there is an
easier way to implement this. Also, how does one account for [M]?
Regards
Amal
