Translations:FEM Solver/58/en

Some of the problems that are intended to be overcome by this solver include
 * Mixed mesh analyses (solid-shell) for dealing with composite columns or prefabricated architectural components: FEM object types.
 * Improved beam and shell elements, as CalculiX's beam elements seem to give wrong results: CalculiX 3-node Beam Element, FEM object types, Example for 1D analysis.
 * Arc-length control for overcoming limit points for elastic-plastic collapse analysis: FEM - Tubular Connection with Shell Elements.
 * Zero-thickness interface elements for various applications, like post-tensioned concrete with friction: pre-stressed pre/post-tensioned concrete bridge.
