Translations:Release notes 0.20/29/en


 * Important: Starting from this release, FreeCAD will use SI units (m, kg, s, K, A, mol, cd) to write the Elmer solver input files (case.sif and mesh.nodes). This is independent of the used FreeCAD unit system.
 * Important: Starting from this release, the scale of result pipelines and their filters will use SI units (m, kg, s, K, A, mol, cd). So the displacement is given in meter, the stress in Pascal. This applies for all SI-derived FreeCAD unit systems.
 * Solving with the Calculix solver now uses all CPU cores. Pull request #6374
 * Meshing with Gmsh now uses all CPU cores. Pull request #6370
 * The element order of Gmsh meshes can be changed via the mesh dialog. Pull request #4660
 * A new constraint was added: . Pull request #4738
 * A new solver was added: . Multiple commits.
 * A new constraint was added: . Pull request #4982
 * It is now possible to have result pipelines with several filters, where some take other filters as input, some take the results directly from the pipeline. commit 708a300b
 * Material cards can now contain values for the electrical conductivity. Pull request #4647
 * Material cards added for Nitrogen and Argon. Pull request #4649
 * Support for the Gmsh mesh algorithms "HXT" (3D) and "Packing Parallelograms" (2D) added. Pull request #4654
 * Allow to set for the Gmsh property High Order Optimize a certain algorithm. Pull request #4705
 * Nonlinear solid materials with simple hardening can now have an arbitrary number of yield points. Pull request #5024
 * Allow modal adding/removal of geometric entities to constraints acting on boundaries. Pull request #5117
 * Most FEM constraint dialogs now behave uniformly and provide the same 3D object selection features. Pull request #5391
