WHAT IS Carat++?

Carat++ is a finite element program for simulation, structural optimization and form finding. Three main features are:

Carat++ is platform independent
Carat++ is suitable for large problems (due to massively parallel programming)
Carat++ is modular and thus easy extensible (due to object-oriented programming)

Standard FE Analyses

The kernel of Carat++ is a general finite element solver. Details can be found here. It offers the following analyses:

• Static (linear/nonlinear)
• Dynamic (linear/nonlinear)
  • Explicit: central difference
  • Implicit: Newmark-β, Generalized-α
• Eigenfrequency
• Linear Buckling
• Contact (Work in Progress)

Structural Optimization

Carat++ comprises a general-purpose optimization toolbox. The main application field is FEM-based shape optimization. Detailed information about the optimization toolbox and its features can be found here.

Form Finding

Carat++ can perform numerical form finding as well as cutting pattern generation. Detailed information can be found in a separate chapter here.
