Marine

From the design and manufacture of small recreational crafts and large oil tankers to the most technologically advanced aircraft carriers, Altair has assisted the world’s leading shipbuilders and boat designers to develop higher performing, safer and lower cost vessels through the application of simulation technology. Altair helps naval architects address complex engineering challenges and mitigate environmental risks associated with seagoing loads including structural, hydro, dynamic, thermal and fatigue, as well as above surface and underwater weapon threats for the military and homeland security.

Simulation for Safer Sailing

Simulation assists the engineering of safer marine vessels and robust offshore structures with modeling of collision, sloshing, slamming, underwater explosive, structural strength assessment, vibration, noise performance, heat and cooling analyses, as well as antenna design. It is important to ensure designs meet industry classification and society regulations, capture knowledge and increase development efficiency through customization and automation technologies and expertise.

Reduce Total Ownership Cost

Increased global competition requires a faster and more efficient ship design and certification process to shorten the turnaround time and reduce cost. To stay competitive in the global marketplace, shipbuilders are looking for ways to reduce production and lifecycle maintenance costs. Increase design efficiency and minimize material usage to reduce manufacturing and operational cost, all while increasing fuel efficiency with Altair’s leading structural and computation fluid dynamics (CFD) optimization technologies.

Tools for Naval Architects

Robust Commercial Ships: Altair OptiStruct™, a modern and more accurate alternative to NASTRAN, can resolve all the typical problems in strength, stress, vibration and noise, bulking, fatigue and thermal analysis. Building upon the solver capabilities of OptiStruct®, Altair HyperLife™ provides a comprehensive and easy to use durability analysis workflow directly interfacing with major finite element analysis result files. OptiStruct is the original topology optimization structural design tool.

Ready Military Vessels: Altair Radioss™ multiphysics capabilities accurately simulate complex physics problems, such as collision, sloshing, slamming and underwater explosions. Altair Feko™ is considered as the global market leader for antenna placement analysis. It is widely used in naval engineering for most electromagnetic issues, like radiation pattern analysis of communication antennas, the placement of antennas, antenna coupling or interference, and near-field radiation hazards.

Faster Recreational Boats: Based on the Finite Element Method, Altair AcuSolve™ is a robust and scalable general-purpose CFD solver that empowers users by providing unparalleled accuracy on fully unstructured meshes. OptiStruct is widely used at the world’s most innovative companies for the design and optimization of laminate composites . It delivers optimal ply shapes, the optimal number of plies, and the optimal stacking sequence, all while observing manufacturing constraints.

Tailored Solutions

Custom Software: Tailored and automated simulation workflow processes for evaluating specific requirements and events can accelerate a more robust engineering process for shipbuilders. Altair’s Product Engineer Services team has extensive experience working with top shipyards and classification societies to assist them in developing packaged solution offerings, integrating both commercial and proprietary tools, to consistently evaluate and streamline certification processes.

Automation for Shipbuilding: The Altair Crane CAE Manager is a new process solution for evaluating and improving the block assembly method of ship building, where cross-sections of the superstructure are pre-built, taken to the building dock, and hoisted into position and attached. It uses a set of macros to assist engineers in dockyards sequence for the block assembly of ships. Parametric system-level models use OptiStruct and Altair MotionSolve™ to generate results and HyperStudy enables system performance optimization.
