CAPRI provides a simple and reliable solution to import native CAD parts and assemblies directly into Cart3D. The watertight geometry is optimized for Cart3D use. Experience greater productivity by minimizing the effort and steps needed to import complex CAD models for analysis.
Cart3D is a high-fidelity inviscid analysis package for conceptual and preliminary aerodynamic design. It allows users to perform automated CFD analysis on complex geometry. Cart3D supports many important NASA projects, as well as other projects in government and industry. Cart3D requires geometry in the form of triangulated components. Triangulations must be watertight for performing component intersections and cartesian mesh generation. Triangulations with gaps and errors require significant time and effort to be usable for analysis. Complicated models can take days to fix, and the final result may no longer be true to the original geometry. CAPRI provides direct watertight triangulation of CAD solids with strict criteria on correctness and accuracy. This eliminates inaccuracies and non-value added healing and cleanup steps typically required for preparation of CAD data for meshing. The resolution of the triangulation can be user-defined to meet the analysis requirements. The process to go from CAD to triangulations requires some tuning, but for the most part requires no manual intervention. There are several flexible approaches to deploy CAPRI into your Cart3D workflow depending on the user’s process needs. For more information on CART3D, visit the Cart3D web site.
Testimonials
“Our partnership with CADNexus was productive and efficient; we managed to find solutions to every major problem that we faced along the way.”
Alistair Wood
Advanced Aero Design at Bombardier
“Our optimization results were very succesful using CAPRI CAE Gateway and ModeFrontier. We generated 350 CAD designs and were able select the optimal design for our motorcycle. Your software CAPRI worked correctly !”
Sergio Corbera Caraballo
UPM-Motostudent Team
“Previously, if we received CAD geometry, it first had to be converted into a format acceptable for Chimera Grid Tools to read, i.e., unstructured surface triangulation or structured abutting patches. This process has always been very tedious and labor intensive (using commercial grid generation software), and could take days or weeks.”
“The capability to ‘read’ in CAD geometry directly into OVERGRID and then perform surface grid generation on the CAD, was simply not available until we had the CADNexus CAPRI CAE Gateway integration.”
Dr. William M. Chan
NASA Ames
“CAPRI is a very easy environment to use for CAD integration, and within a short amount of time we incorporated direct CAD model access in our grid generation system.”
Dr. Mike Remotigue
ERC SimCenter
“From my experience, CAPRI CAE Gateway is a unique software primarily because of its direct connection to CAD and overall robustness. I can use an in-house geometry manipulation and triangulation tool, but I find that the time to take something out of CAD and put the final design back into CAD is prohibitive. We have performed over 10,000 automated CFD design iterations using CAPRI for CAD integration, with parametric update and surface wrapping reliability exceeding 99.98%.”
Marian Nemec, Ph.D., ELORET Corporation
NASA Ames Research Center
“Typically our research requires access to a range of geometric and topological information which can sometimes be difficult to access (and manipulate) using traditional CAD methods. The CAPRI CAE Gateway provides a neutral platform to enable us to easily access this information for a number of CAD systems.”
Dr. Trevor Robinson
Queens University Belfast
“The CADNexus CAPRI CAE Gateway provides a means of enabling an associative link between our CAD and CAE environments, which is an important part of our PLM strategy.”
Dr. David Venditti
Analytical Lead – PLM Group, Pratt & Whitney Canada
“The CAPRI CAE Gateway software from CADNexus is proving to be of great value in moving a geometry quickly and accurately from a CAD model to the start of the CFD analysis process u sing OVERFLOW.”
“We have been experiencing the use of the CAPRI as a gateway to native CAD models for our multidisciplinary optimization system. CAPRI CAE Gateway is really a breakthrough in CAD model management, the first tool with a seamless interface to all major CAD packages. As a player in the Aeronautics business, CAPRI CAE Gateway provides us with direct interface to parametrized parts, it enables to directly optimize the part in its native format and provide the customer with a final optimized shape without any artificial CAD translation.”
Dr. Michel Delanaye
General Manager, CENAERO
“CAPRI CAE Gateway proved to be invaluable in our development of a CAD-based geometry control system for aerodynamic optimization. CAPRI simplified the integration with CatiaV5, so that the geometry could be manipulated directly within the CAD environment for design optimzation.”
