[petsc-dev] Another SSP method

[Emil Constantinescu]

Matt, they seem to be provided in Butcher tableau form in the paper. One 
can register an RK method and use it.

An example (for ARKIMEX) is here:

Someone from my class requested

   R. J. Spiteri, S. J. Ruuth, A new class of optimal high-order 
strong-stability-
preserving time discretization methods, SIAM J. Numer. Anal. 40 (2002) 
469-491.

which is a fourth order, five stage method that we do not appear to 
have. How hard is this to add?

   Thanks,

      Matt
