Elmer Release Notes for version 9.0 Previous release: 8.4 Period covered: Dec 18 2018 - Nov 10 2020 Number of commits: ~1340 (excluding merges) These release notes provide information on the most essential changes. You can get a complete listing of commit messages, for example, with: git log --since="2018-12-18" > log.txt Apart from the core Elmer team at CSC (Juhani K., Mika M., Juha R., Peter R., Thomas Z.) git log shows contributions from Daniel B., Denis C., Eef v. D., Eelis T., Fabien G-C, Foad S. F., Fredrik R., Olivier G., Joe T., Luz P., Mondher C., Rupert G., Sami I., Sami R., Samuel C., and Saeki T. to this release. Additionally there are many ongoing developments in several branches that have not been merged to this release and are not therefore covered here. Also sometimes the code has been passed on by the original author by other means than the git, and in such cases the names may have been accidentally omitted. The contributions of all developers are gratefully acknowledged! New Solver Modules IncompressibleNSVec Incompressible Navier-Stokes solver utilizing vectorized and threaded assembly Includes built-in support for block preconditioning (Schur complement approximation included) Includes non-Newtonian material laws Intended for Elmer/Ice community but also other may find it useful. BeamSolver3D Solver for the Timoshenko equations of elastic beams embedded in 3-D space (see Elmer Models Manual for documentation) GmshReader Reads the mesh and results from simple Gmsh file format (that can be written by ElmerSolver as well) Solver includes interpolation of the fields to the current mesh May be used for hierarchical simulations where results are inherited from previous simulations ModelMixedPoisson A general-purpose mixed FEM solver for the Poisson equation (see Elmer Models Manual for documentation) Employs a div-conforming (face) finite element approximation SpringAssembly A generic utility to add node-wise springs and masses to structural models (see Elmer Models Manual for documentation) ...
