For analysis, the SDT provides a general finite element architecture that can be used in all fields (multi-physics modeling) and a range of specialized solvers to create models used to study vibration problems.

For test, all the tools for experimental modal analysis and related operations are provided in an open and programmable environment.

Key Features for Analysis
  • General 3-D Finite Element Modelling with an open architecture allowing easy user development of new multi-physics elements, …
  • Key compiled functions allow treatment of large models.
  • .m files for efficient implementation of major solutions (non-linear statics and time integration, eigenvalue, …)
  • Graphical User Interface (GUI) visualization tools let you build on the MATLAB/SDT ease of use to pre-/post-process computations done using SDT or other codes
  • Model reduction, substructuring and system model building
  • Physical parametrization of FEM models for optimization or updating
  • Data structures fully compatible with popular FEM codes (NASTRAN, ANSYS, ABAQUS,…)
Key Features for Tests
