Detailed Description

Boundary condition solver (semi-analytic algorithm)

This boundary condition solver uses the semi-analytic algorithm to solve the boundary value problem in two stages. Firstly, a two-scale iteration is performed to solve for a subset of the parameters. Once these are determined, semi-analytic solutions for the remaining parameters are calculated at the relevant scales.

◆ solve()

void flexiblesusy::RGFlow< Semi_analytic >::solve ( )

solves the boundary value problem

Solves the boundary value problem.

At first the initial_guess() is called. Afterwards, the semianalytic solution is applied: first, the function iteratively runs the tower up and down and imposes the boundary conditions. The iteration stops if either the maximum number of iterations is reached or the precision goal is achieved (defined by the convergence_tester for the inner two-scale iteration). Then the next, semianalytic step is applied. This is iterated until either the maximum number of iterations is reached or the precision goal is achieved (defined by the convergence_tester for the outer iteration).
