船舶
從設計和製造小型休閒船、大型油輪到技術最先進的航空母艦，Altair 透過應用模擬技術，幫助世界領先的造船廠和船舶設計師開發出效能更優異、更安全、成本更低的船舶。Altair 幫助造船工程師應對複雜的工程挑戰，降低與航海負載相關的環境風險，包括結構、水力、動力、熱力和疲勞，以及水面和水下武器對軍事和國土安全的威脅。
借助模擬實現更安全的航行
模擬協助工程師設計更安全的海洋船舶和堅固的離岸結構，包括碰撞、搖晃、猛擊、水下爆炸、結構強度評估、振動、噪音表現、熱和冷卻分析，以及天線設計。重要的是，要確保設計符合行業分類和社會法規，獲取知識，並通過定製和自動化技術及專業知識提高開發效率。
降低總擁有成本
隨著全球競爭加劇，造船公司必須提高船舶設計和認證流程的速度及效率，縮短交付週期，降低成本。 為在全球市場保持競爭力，造船公司紛紛尋求能夠降低生產成本和生命週期維護成本的方法。借助 Altair 領先的結構和計算流體動力學 (CFD) 優化技術，可提高設計效率，並最大程度地減少材料用量，從而降低製造和營運成本，提高燃油效率。
專為造船工程師而設計的工具
穩健的商用船：Altair® OptiStruct® 提供幾乎在每個行業使用的增強專利版 NASTRAN。OptiStruct 提供可用於線性、非線性、振動、聲學、疲勞和多物理場分析的求解器。借助 OptiStruct 的求解器功能，Altair® HyperLife® 提供了一個全面且易於使用的耐久分析工作流程，可直接與主要有限元分析結果的檔案串聯。OptiStruct 是原始拓撲優化結構設計工具。
可隨時投入戰鬥的軍事船舶：Altair® Radioss® 多物理場功能可以準確仿真複雜的物理問題，例如，碰撞、晃動、衝擊和水下爆炸。Altair® Feko® 被認為是天線佈局分析領域的全球市場領導者。這款軟體廣泛用於海軍工程領域，可解決大部分電磁問題，如通信天線的輻射方向圖分析、天線佈局、天線耦合或干擾以及近場輻射危害等。此外，WRAP™ 是 Altair® Feko® 的元件，可為海上船隻提供安全可靠的通信，確保沿海水域不會出現干擾或覆蓋缺失的盲點。
速度更快的休閒船：Altair CFD™ 以有限元方法為基礎，是一款可靠且可擴展的通用 CFD 求解器，可以對完全非結構化的網格做出無比精確的分析，並為使用者提供幫助。全球最具創新力的公司紛紛將 OptiStruct 廣泛用於設計優化層壓複合材料。該工具能在完全遵守製造約束條件的情況下，提供最佳的層形狀、理想的層數以及合理的鋪層順序。

A Simulation Driven Approach for Evaluating & Improving the Block Lifting Method of Ship Building
This session will introduce you to the Crane CAE Manager from Altair, which is a radically different solution that provides unique advantages for Block Lifting Method consisting of:
1. Build - Specific Block Systems
2. Analyse - The planned lifting operations using simulation methods
3. Evaluate - Safety aspects of the planned lifting operation
4. Improve - The system behavior
Improving Rudder Shock Loading Following a Nearby Blast Event Using Radioss
Engineers in the Marine, Shipbuilding, and Offshore industries face many design challenges including physical space constraints, extreme weather conditions, deep water and remote locations. These constraints create an extreme environment for the engineer to develop a sound, reliable and safe operating platform.
Creating a Structurally Efficient Design for the Queen Elizabeth Class Aircraft Carrier
When making key decisions at the concept and preliminary design phases of a naval ship project, the designer is often obliged to work with limited data on the major structural design drivers for the vessel. This can lead to a largely subjective design approach which can result in inefficiency and even structural problems being locked-in from the start. To solve any issues, increased material use, weight and unnecessary complexity, as well as high design and manufacture costs can be introduced to the end product. To evaluate the potential of simulation-driven design under the unique requirements of naval ship design, the ACA partnered with Altair ProductDesign.
Taking on the Shell XPRIZE with Help from a Digital Twin
Chris Wilkinson, CTO at SMD speaks at the UK Altair Technology Conference 2019. An XPRIZE challenge is designed to source new approaches to solve difficult problems thereby disrupting existing markets or creating new ones. Our oceans cover over 70% of the planet with only 5% explored. The ocean environment is hostile and technically challenging to operate within. The Ocean Discovery XPRIZE competition was established to seek cheaper and faster solutions to survey the world’s oceans. This presentation is about one of the teams that entered the competition with a disruptive solution for ocean survey. The emerging role and importance of a digital twin is explored to support the solution as it scales from proof of concept to one that is fully industrialised.
