Oasys 套裝軟件是專門為LS-DYNA而開發的，Oasys是前/後處理軟件市場上的具有領先地位的軟件工具，並被全球許多最大的LS-DYNA客戶所使用。
Oasys 套裝軟件最新版本9.3 為客戶提供了更多的工具與新功能，有效減少了LS-DYNA模型的建立與檢查所需要的時間，使得工程師更專注於手頭的實際問題，而不必耗費大量時間用在運行和測量 LS-DYNA上，有效提高生產效率。
Oasys 被用於分析材料結構的非線性變形。 系統充分地使用了自動化的高級算法分析，並且各種各樣不同的物質模型，允許用戶模擬全世界解決真實環境的復雜問題。 在Arup Oasys幫助下分析金屬結構的變形，車輛緊急情況，以及地震沖擊或爆炸的作用。 另外軟件准許使用它分析問題用以物理上各種各樣的區域。


Software used to analyze the nonlinear deformation of the structures of materials. The system used a fully automated high-level algorithm analysis, as well as a wide range of different material models, which allows users worldwide to solve complex problems of the real environment. With the help of Arup Oasys program analyzes the deformation of metal structures, vehicles emergency situation, as well as the effects of seismic impact or explosion. In addition the software allows to use it to analyze problems in various areas of physics.


Crashworthiness Simulation
For many automotive companies LS-DYNA is a tool for understanding the deformation of complex systems such as vehicle structures. The ability of LS-DYNA to model contacts and its wide range of material models make it ideally suited for this type of analysis. It also includes a number of specific features for automotive applications such as:
Spotweld Models
Airbag Models
Seatbelt System Models


Occupant Pedestrian Safety Analysis
Providing crash protection for occupants and pedestrians is an integral part of modern vehicle development. A range of fully validated FE models of the major physical test devices is available for LS-DYNA. These include:
Hybrid III 50th Percentile Male Dummy
Hybrid III 5th Percentile Female Dummy
EuroSID-II Side Impact Dummy
US-SID Side Impact Dummy
SID-IIs Side Impact Dummy
Pedestrian Headform Impactors
Pedestrian Legform Impactors


Metal Forming
LS-DYNA has been used for sheet metal stamping since the late 1980's and can be used to assess a proposed forming process and tool design. Along with the forming process you can also simulate trimming and springback. LS-DYNA has the capability to analyse a variety of different forming processes including:
Rigid Tool Stretch and Draw Forming
Sheet and Tube Hydro Forming
Flex Forming
Roll Forming
Superplastic Forming


Drop Testing
LS-DYNA has been used to simulate impact events of different containers for many years. Ranging from small electronic products such as mobile phones and laptop computers, up to large nuclear fuel containers. Features include:
Fluid Structure Coupling (ALE / SPH) for modelling liquid filled containers
Element Free Galerkin (EFG) for modelling cracks
Explicit-Implicit switching for studying steady state deformation


Seismic Analysis
LS-DYNA provides engineers with a tool for modelling the complex nonlinear behaviour of a building during seismic events. Non-linear response history analysis can be performed using element types and functions including:
Lumped plasticity
Fibre elements
Nonlinear dampers
Buckling elements
Frequency-dependent damping
These features make LS-DYNA an ideal tool for engineers practising performance-based earthquake engineering.
