{| cellpadding=5 Forum discussion, Analysis of reinforced concrete with FEM (tutorial) | Pull request #2267.
 * Femconcrete_Wall_3D_rx_PSS.png
 * After half a year in development and testing the "femconcrete" branch was added to the FEM Workbench. This provides tools to estimate the level of reinforcement required in a concrete structure to prevent brittle failure under tension or shear. In essence, it is a post processing routine for the CalculiX solver, which calculates the principal tensile stresses in the concrete from an elastic analysis and uses those to determine the minimum reinforcement in the three coordinate directions required to prevent failure.
 * fcFEM_Plate_with_Hole_2.png
 * After a few months in development the "fcFEM" macro was published. It implements a finite element solver entirely in Python. Its author designed it to overcome the limitations of other external solvers, like CalculiX and z88. Some of the intended improvements include creating mixed mesh analyses, improved beam and shell elements, arc-length control for overcoming limit points in elastic-plastic analyses, implementation of zero-thickness interface elements for different applications, and others.
