(Program features marked are optional and may not be available on all installations.)*

Additional features include

  • Sets of nodes may be constrained to act either identically in specified directions, or to act as a rigid body in specified planes.
  • Loads may be applied on nodes, on elements or on surfaces representing floor or walls etc. In addition to forces and moment applied to the structure, load types include gravity, prestress, thermal and distortion loads.
  • Restraints and constraints can apply to non-global and user defined axis directions as well to global axis directions
  • Displacements and forces are calculated at automatically determined intermediate points along 1D elements.
  • Beam sections may be selected from a steel section database, which includes British, European, US and Australian sections. Other options are to specify the dimensions of a general section (rectangular, circular, I-section, etc.) or to specify the properties required for analysis explicitly.
