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. Versions of this program held in the CPC repository in Mendeley Data AEPB_v1_0; FlowPy; 10.1016/j.cpc.2013.03.002
