FlowPy—A numerical solver for functional renormalization group equations

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)

Abstract
FlowPy is a numerical toolbox for the solution of partial differential equations encountered in Functional Renormalization Group equations. This toolbox compiles flow equations to fast machine code and is able to handle coupled systems of flow equations with full momentum dependence, which furthermore may be given implicitly.

Title of program: FlowPy
Catalogue Id: AEPB_v1_0

Nature of problem
In the study of functional renormalization group equations non-local integro-differential equations arise which furthermore can contain singular coefficient functions for the highest derivative and may only be given implicitly. Solving these equations beyond the simplest cases thus provides a numerical challenge.
