3D FEM ultimate/ultimate 50

The high-end packages for structural engineering

The 3D FEM ultimate and ultimate 50 packages provide all the tools for modern structural analysis in civil engineering and bridge design. In addition to the graphical input capability by the AutoCAD® add-on SOFiPLUS, the parametric axis - related graphical modeling CABD or the Master-cross section which allows any cross sectional profile, can be used.

The usage of Pre- and post-tensioned beam- and shell-elements, along with the ULS and SLS design and stress checks offer the capability of project analysis of  prestressed concrete and composite systems. Full geometrically nonlinear analysis (Theory of 3rd order) gives the possibility for cable and shell buckling calculations. Traffic load calculation with influence line method and a large library of road and railway loads, is also available to the user. High-end SOFiSTiK technologies such as DYNA for dynamic analysis and HASE for semi-infinite solid simulation can be added optionally.

Ultimate 50 comprises all features from the 3D FEM ultimate package with the limitation to a maximum project size of 50m x 50m x 20m.
