Detailed Description

template<class TSparseSpace, class TDenseSpace>
class Kratos::ExplicitSolvingStrategyBFECC< TSparseSpace, TDenseSpace >

Explicit Back-and-Forth Error Compensation Correction time-integration scheme.

:

This scheme evaluates the residual three times per step and has quadratic accuracy in time. Will only work for formulations reading from buffer positions 0, and 1. Behaviour when reading from buffer position 2 or greater is left unspecified.

Formulation:

First, a Forward-Euler step is taken from t=t0 to t=t0+Δt. u1 = u0 + Δt*(M^-1)*R(u0)
Then, a Forward-Euler step is taken backwards back to t=t0 u2 = u1 - Δt*(M^-1)*R(u1)
Then, an error is computed from the diference between u0 and u2: e = (u2 - u0) / 2
A corrected u is computed: uc = e0 - e
Then, a last Forward-Euler step is taken from the corrected value at t=t0 to t=t0+Δt: u = uc - Δt*(M^-1)*R(uc)

Note that for this scheme to work, the formulation must preserve information during steps 1 and 2. Hence, all non-numerical dissipative terms must be disabled during these back-and-forth steps for the correction to make sense.

The following methods are provided in order to extend this class:

void InitializeBFECCForwardSubstep() - Executed right before 1.
void FinalizeBFECCForwardSubstep() - Executed right after 1.
void InitializeBFECCBackwardSubstep() - Executed right before 2.
void FinalizeBFECCBackwardSubstep() - Executed right after 2.
void InitializeBFECCFinalSubstep() - Executed right before 5.
void FinalizeBFECCFinalSubstep() - Executed right after 5.
