General Features (excerpt)
- Beam elements (rigid offsets and semi-rigid joints, too), beam on elastic foundation, truss, thin or thick plate (3 or 4 nodes), plate on elastic foundation, membranes (3 or 4 nodes), spring, solids (4, 6, 8 nodes).
- Selective, complete and reduced integration.
- Wilson-Ibrahimbegovic formulation.
- Eccentricities.
- Semi-rigid joints.
- Versions limited to increasing node-number, up to no-limits but due to RAM available.
- Automatic mesh control commands (double nodes, double elements, unreferenced nodes, lack of constraints conditions, etc).
- Cross-sections archive having more than 14,000 units, upgradeable and accessible via design filters to choose needed cross-section.
- Full interface with SAMBA (in bundle with SARGON).
- Superelements (set of aligned straight beam elements checked as one member).
- Bidirectional interface with Strucad (.anf, .arf). Standard interface with 6 external solvers.
- Listing in Italian, English or Spanish.
- Internal forces diagrams, envelopes, envelopes of envelopes.
- Deformed shape using spline and internal to element inquire of the displacements.
- Solid view of elements.
- Constraint reactions and envelope of the constraint reactions.
- Colour maps with the stresses in bi- and tri- dimensional elements: principal stresses, Von Mises, Tresca, tensor Invariants, tensor components.
- Error control.
- Adaptive refinement.
- SRSS, CQC, modal amplification methods.
- Tables with the effective mass percentages.
