As the world becomes more connected, the Marine Engineering and Shipbuilding Industry is becoming even more important due to its role in transportation, trade and energy delivery. Due to increased global competition, the ability to accelerate turnaround time and to reduce cost is becoming a key driver to success. The use of simulation technologies to improve design efficiency and reduce physical testing costs continues to be one of the best ways to address engineering challenges in Marine industry.
The Altair HyperWorks software suite is designed to handle this type of challenging environment, and the industry is recognizing that. More and more maritime classification societies and leading shipyards have adopted HyperWorks as the next generation simulation technology to meet maritime industry needs.
HyperMesh, HyperView, OptiStruct, HyperStudy, RADIOSS, AcuSolve and FEKO are the next generation simulation technologies being used by the maritime industry today.
“Together with Altair, a number of opportunities were identified to use HyperMesh and OptiStruct for the analysis of local structures and identification and removal of redundant material, leading to weight and cost saving benefits.”

Structural and CFD Optimization
Altair leads the world in optimization technologies and those technologies have been applied in many different industries over the decades.
Maritime professionals can derive optimum solutions that meet design requirements with the minimum possible material mass and welding effort. This results in a ship that is less expensive to manufacture and maintain. Maritime professionals also can optimize the hull shape to reduce water resistance to increase fuel efficiency and reduce operational cost.
- Create efficient vessel and structure design using topology optimization to lead to designs with better stress distributions and longer fatigue life with the award winning structural optimization tool, OptiStruct.
- Optimize the thickness of steel plates and size plate stiffeners automatically across the whole ship using size and shape optimization in OptiStruct.
- Reduce water resistance to cut fuel costs using the optimization tool HyperStudy together with the CFD solver AcuSolve.
- Reduce weld length and fabrication cost through structural optimization.
- Quickly determine optimum composite ply layups and orientations for navy vessel and boat structures using the most advanced composite optimization capability in OptiStruct.
HyperWorks offers comprehensive solvers to meet marine vessel engineering simulation needs.
OptiStruct, RADIOSS, AcuSolve and FEKO help maritime engineers meet classification societies’ requirements and answer owners’ concerns through simulation of a variety of linear, nonlinear, thermal, fluid-structure interaction, CFD and electromagnetic problems to ensure marine vessels’ safety, reliability, and durability.
- OptiStruct, a modern and more accurate alternative to NASTRAN, can resolve all varieties of typical problems in strength, stress, vibration & noise, bulking, fatigue and thermal analysis.
- Accurately simulate complex physics problems, such as ship collision, sloshing, slamming and underwater explosions with RADIOSS’ multi-physics capabilities.
- As comprehensive electromagnetics code, FEKO is considered the global market leader for antenna placement analysis. It is used widely in naval engineering for most EM issues like radiation pattern analysis of communication antennas, the placement of antennas, antenna coupling or interference, and near-field radiation hazards.
- Based on the Finite Element Method, AcuSolve is a robust and scalable general-purpose CFD solver that empowers users by providing unparalleled accuracy on fully unstructured meshes. It is a fully coupled solver on shared-memory and distributed parallel systems that is highly accurate in space and time.
Customization and Automation
To achieve the goal of creating a safer, greener and smarter maritime industry, regulations have been reinforced with even tighter requirements which involves more simulations. Additionally increased global competition requires a faster and more efficient ship design and certification process to shorten the turnaround time and reduce cost. This makes efficient handling of many large scaled complex FE-models with vast numbers of complicated loads and multitudes of fatigue check points a key challenge for the industry.
The Altair engineering team has extensive experience leveraging our process automation and data management technology for many top shipyards and classification societies to assist them in developing efficient and automated custom tools and programs that meet specific customer needs and speed up the verification and certification process.
Altair process automation technologies enable maritime engineers to dramatically improve efficiency and capture corporate best practices and industry standards for certifications. It can automate and standardize repetitive modeling and processing tasks including:
- Import, organize and idealize geometry
- Mesh generation for beam, shell and solid elements
- Welds and connections
