The fundamental equation governing linear static problems in Finite Element Analysis (FEA) tools like Abaqus is KU = F, where the global stiffness matrix (K) multiplied by the unknown displacement vector (U) equals the external force vector (F). This equation captures the complete physical behavior of the system, including material stiffness, geometric properties of the
In a CFD simulation (see FMK in the 3DEXPERIENCE and PowerFLOW) that involves wall-bounded flows, it is crucial to accurately predict the behavior of the turbulent boundary layer. Accurate prediction of the turbulent boundary layer dictates the ability of the CFD simulation to accurately predict forces exerted by the fluid on the solid surfaces such
Fatigue refers to weakening of the material when subjected to repeated loads. In real life scenario, take a paperclip which is robust and strong at the beginning of its life. But when it is used repeatedly, you observe that it becomes easier and easier to bend. It might eventually break at a force far less
Creep failure occurs in a material when it is subjected to constant load over prolonged periods of time. This is permanent deformation occurring in the material due its inherent atomic or molecular structure. This failure occurs when the stresses are well below the yield stress of the material. Understanding and accounting for creep behavior is
Simulation in engineering product development provides numerous benefits that enhance efficiency, accuracy, and innovation. By taking advantage of virtual models to simulate real-world conditions, engineers can predict how a product will perform under various scenarios without needing physical prototypes. This reduces costs, as it minimizes the need for multiple physical tests. Simulation also allows for
When it comes to purchasing complex software like Abaqus, our industry-leading finite element analysis (FEA) tool, many customers face a choice: should they buy directly from the software provider or work with a Value-Added Reseller (VAR)? While direct or online purchasing might seem convenient, there are numerous reasons why partnering with a VAR is often

PowerFLOW is an inherently transient Lattice Boltzmann-based CFD software by Dassault Systemes that performs fluid flow simulations that accurately predict real world conditions. The PowerFLOW suite facilitates high-fidelity, scale-resolving simulations, empowering engineers and designers to assess product performance early in the design process through digital prototyping, ultimately conserving time, resources, and budget. PowerFLOW is widely
In the ever-evolving world of digital innovation, companies across industries strive to streamline their software licensing strategies for enhanced efficiency, cost savings, and seamless user experiences. Our partner, Dassault Systèmes, a leader in 3D design, engineering, and Product Lifecycle Management (PLM) solutions, recognized this need and responded by introducing a transformative approach—its Unified License Model
Heat transfer is the transfer of thermal energy in the form of heat from one system to another. For example, consider a pot of water being heated by an electric stovetop. Here, heat is transferred from the hot stovetop to the pot, from the pot to the water, and from both the heat pot and
