FEM Workbench

 * GUI FEM commands have keyboard short cuts now. An preference dialog for FEM was introduced. The binary path of CalculiX is one of the preference settings.
 * GUI analysis container Analysis member uses drag & drop. They can be moved in and out of a analysis container. Since there is now support for multiple analysis, member can be moved into another analysis too. Multiple constraints can be created in an analysis.
 * GUI one click analysis A one click analysis button has been added to the GUI. It does purging results, writing CalculiX input file and does the analysis for the selected solver. It is detected if multithreading is available for CalculiX and uses the maximum possible threads.
 * Input file FreeCAD's build-in editor supports editing CalculiX input files (*.inp). Syntax highlighting was implemented too.
 * Netgen mesh object The GUI and property editor of the Netgen mesh object has been reworked. Tetraeder meshing off one order and second order elements is supported as well as adjusting meshing parameter.
 * Constraint force and constraint fix objects It is now possible to add Forces and Fixes on edges and Vertexes.
 * Constraint pressure object A new object for pressure load on faces has been added. The pressure (load per area) is passed directly to CalculiX which means the node loads are not calculated by FreeCAD but CalculiX instead.
 * Constraint prescribed displacement object A new object for prescribed displacements has been added. The prescribed displacement can be added to vertexes, edges and faces. For shell and beam analysis’s it is possible to fix the rotational degrees of freedom.
 * Beam section object The new beam section object allows to define rectangle cross section for beam FEM. There is support for different beam sections in one analysis by defining reference shapes for each cross section
 * Shell thickness object The new shell thickness object allows to define thicknesses of shell plates. Like in beam section there is support for multiple shell thicknesses in one analysis by defining reference shapes.
 * Material object Multiple materials are supported for edge, shell and solid meshes. Like for the beam section and shell thickness objects a appropriate FEM Mesh is needed to use the multiple material.
 * Solver object As a base for multiple solver a solver object has been implemented. All analysis properties moved from analysis to solver.
 * Frequency analysis A frequency analysis can be made. The number of eigenvalue or eigenshape to calculate can be adjusted in preference GUI.
 *  View provider Shell and beam FEM-Meshes can be viewed in FreeCAD and thus the results of such analysis too.
 * Python API Methods for working with FEM-Meshes and making an Analysis from python have been added.
 * GMSH Macro An interesting external developing is the Macro_GMSH which makes it possible to use GMSH for meshing. Very useful for all not able to compile FreeCAD with Netgen or for meshing shell- or edge meshes.
 * General Improvements Due to the heavy development taking place, there have been tons of improvements on the code base of FEM module.
