METEOR (Method of unified complete result) Enhanced options for MODEL VARIATION system. New system that enables the user to merge problems with the same topology – nodal coordinates, FE model, geometry of sections. Problems may differ in load cases, stiffness and boundary conditions. The merged problem will contain topology, stiffness, design options of the basic problem and analysis results of all problems. For such merged problem the user will define and calculate unified DCF. Design procedure is carried out according to these DCF by specified design options.
