explicit euler equations usually have long convergence times. Is it possible to have an implicit time stepping instead to make the time step better? I am not meaning runge kutta methods. My own numerical method is finite volume with Roe' scheme.

I suggest to use a BDF method in where the solution of the implicit non-linear system is obtained by means of a modified Newton-Raphson scheme, with a dual time step integration technique (*)
