Detailed Description

template<class TSparseSpace, class TDenseSpace, class TButcherTableau>
class Kratos::ExplicitSolvingStrategyRungeKutta< TSparseSpace, TDenseSpace, TButcherTableau >

Family of explicit Runge-Kutta schemes.

: Formulation:

The differential equation is u_t = f(t, u)

The Runge-Kutta method is, for i = 0...N substeps:

k^(i) = f(t + c_i*dt, u^(i-1)) -> Where u^(0) := u^n
u^(i) = u^n + \sum_{j=1}^{i-1} A_{ij} k^(j) -> Intermediate steps. u^(N) is not needed, therefore neither is A[N, :]
u^{n+1} = u^n + \sum_{i} b_{i} k(u^(i)) -> Solution

Template Parameters

TSparseSpace
TDenseSpace
TButcherTableau	specifies The sets of coefficients A, b and c The number of Runge-Kutta substeps
