WHAT IS Carat++?
Carat++ is a finite element program for simulation, structural optimization and form finding.
The software is the result of a complete redesign of CARAT, the research code at the Chair of Structural Analysis, Prof. Dr. K.-U. Bletzinger, TU Muenchen.
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)
- Interface for coupled analyses like fluid-structure interaction (FSI)
Isogeometric Analyses
The kernel of Carat++ is also a general finite element solver for isogeometric analysis (IGA). Details can be found here. It offers the following analyses:
- Static (linear/nonlinear)
- Form Finding
- Eigenfrequency
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.

 Eigenfrequency optimization of a car rear shelf |
Form Finding and Cutting Pattern Generation
Carat++ can perform numerical form finding as well as cutting pattern generation. Detailed information can be found in separate chapters here.
