FELYX is an object oriented Finite Element Method (FE/FEM) code written in C++. Further, FELyX is an open source software freely accessible for everyone.

The main motivation to write FELyX was to have a free and object oriented Finite Element code that is numerically efficient and allows to access the Finite Element calculation at any level. Dependence of the optimization, the access to all kind of information is requested. Hence an efficient postproccesing structure is also a main topic.

FELyX is also used in other fields like LCM calculations or smart structures.

Since the start of the project the finite element library was already used for a number of applications, e.g.

Implementation of minimum compliance topology optimization methods
Liquid Composite Molding (LCM) process simulation
Specialized element formulations for composite materials
Implementation of new failure criteria for composite materials
Implementation of new iterative solver strategies for the special purposes of optimization
Realization of mesh-coupling algorithms for our structural-fluid coupling software
