Dear GetFEM++ users,
GetFEM++ 5.0 is released. This is a major release of GetFEM++. The main evolution is the generalization of the use of the high-level generic assembly for a more easy writting of nonlinear coupled problems. The few incompatibilities come from the fact that a certain number of tools have been re-designed (mainly Nitsche’s bricks and time integration schemes) and the old brick system (from 1.7 release) have been definitevely unplugged. The main changes are: - Standard bricks (generic elliptic, elasticity ...) are now based on the high-level generic assembly. - Nitsche’s bricks have been re-designed. - The support for time integration schemes has been re-designed. - The support for large sliding contact has been improved (still a work in progress). - Import of GMSH meshes has been improved. - New tutorial and new Python/Scilab/Matlab demos. - Allowing tensor field for model data. - Cleaning/deletion of some obsolete files, including the old brick system. - MPI and OpenMP parallelization of the high-level generic assembly. - The use of mu_parser have been replaced by the use of the high-level generic assembly language. mu_parser in no longer a dependence of GetFEM++. - Add of “elementary transformations” in the high-level generic assembly to allow for instance a local projection of a finite element on a lower level element to perform a reduction such as the one used in MITC element. - Macro definition in the high-level generic assembly language. - Numerical continuation/bifurcation detection/branching improved. - Matrix exponential and logarithm operators added to the high-level generic assembly. - Allowing the use of C++11 feature. - New im_data object version to store and interpolate data on the gauss points of a boundary. -- Yves Renard Personnel INSA Tel. +33 (0)4 72 43 87 08 INSA Lyon - ICJ - LAMCOS - GMD Campus LyonTech-La Doua 20 avenue Albert Einstein 69621 Villeurbanne cedex www.insa-lyon.fr _______________________________________________ Getfem-users mailing list [email protected] https://mail.gna.org/listinfo/getfem-users
