New functionalities of Versions 5.0 and 5.1 of the TFEL/MFront project and Versions 3.0 and 3.1 of the MGIS project

As part of the open-source TFEL project, MFront simplifies the implementation of complex mechanical behaviours efficiently and portably across various finite element and FFTsolvers. This paper highlights important new features introduced in TFEL/MFront Versions 5.0 and 5.1. It also outlines how the MFrontGenericInterfaceSupport project enables straightforward integration of MFront behaviours into a range of open-source or commercial solvers.
