Welcome to the Carat++ wiki! The purpose of this resource is

  • to promote collaboration between Carat++ users.
  • to offer a forum for questions, discussions and suggestions about Carat++.
  • to provide a basic knowledge base that can be used by both existing and new users
  • to demonstrate the capabilities of Carat++ (perhaps after some time).


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. More detailed information about the features of Carat++ can be found here.
