Boosting simulation driven design with CAD software

Paul Boughton

As a result of the merger between DNV and Germanischer Lloyd, DNV GL is now strengthening its design and engineering software by expanding its Sesam portfolio with the product Sesam CAESES (Computer Aided Engineering System Empowering Simulation). The product supports upfront design optimisation in the maritime, offshore and mechanical industries.

With Sesam CAESES users can improve hydro- or aerodynamic performance of designs, to achieve lower resistance and reduce pressure drop, for example. This leads to higher energy efficiency of ship hulls, propellers, engines and turbo-machinery, improving environmental and business performance.

Sesam CAESES was previously marketed as Friendship-Framework, part of Germanischer Lloyd’s software portfolio. “Friendship-Framework has long been recognised as leading software within its field,” says DNV GL – Software managing director Are Føllesdal Tjønn. “We are proud to include it now as Sesam CAESES in the Sesam family of products for design and engineering.”

With Sesam CAESES engineers can carry out numerous simulations to optimise designs. It integrates with most of the leading commercial CFD (computational fluid dynamics) codes as well as in-house codes. It can be integrated with other Sesam modules in the design optimisation process. Multiple modules can be involved allowing for complex simulation scenarios.

Sesam CAESES is based on a powerful and flexible 3D parametric modeller (Upfront CAD). With this software addition DNV GL will continue to support customers in many different industries that benefit from simulation-driven design such as the maritime, offshore, automotive and mechanical industries.
