Dear Christophe,
    Can we use some explicit method at each time step instead of solving a
big linear system while solving wave equation in GetDP? This will save a lot
of computation time especially when I have thousand of time steps. If it can,
do we have much trade off in accuracy? By the way, thank you for your
comments on the Perfectly macthing absorbing layer.
