Fluid-Structure Interaction Analysis without the Fluid in FEA Models
Fluid-Structure Interaction (FSI) routinely occurs during the operation of subterranean equipment in the oil and gas industry. Analysis of these downhole tools needs to account for this interaction. The interaction between a fluid and a structure can be strong or weak. For many weak interactions, the fluid effects can be represented by equivalent loads, such as hydrostatic pressure, and a regular finite element analysis (FEA) is sufficient. For other cases of weak interactions, the effects of the fluids on the structure can be determined a priori and then used as an input for structure analysis, or vice versa. For strongly coupled FSI, a fully coupled FSI analysis is required, which is substantially much more complicated than the simplifications available with a weakly coupled FSI. Understanding the opportunities for using a weakly coupled FSI can result in great time savings. There are some scenarios where the fluid and its effects can be modeled fully within FEA models in Abaqus. In this presentation, our work (Ref 1-3 as examples) on FSI analysis without fluids in the FEA models is reviewed. It is shown to be efficient and accurate for selected types of applications.

Model-Based Approach for Re-evaluating the Multi-Discipline Performance of a Check Valve for Hydrogen Processing
Satisfying product requirements for performance, robustness, and quality are longstanding challenges faced during product development. Close collaboration between product managers, designers, and engineers is instrumental to finding the best design candidate, but disconnected tools, data, and people frequently result in a sub-optimal final product with increased risks. Increasing product complexity and sophistication places a renewed emphasis on the importance of satisfying product requirements, highlighting the need for virtual testing environments and realistic multi-physics simulation. The 3DEXPERIENCE Platform rethinks the product development process through a model-based framework enabling seamless data flow between disciplines without the need for data conversion. This results in true collaborative simulation-driven design for all phases of product development with full traceability to product requirements. Design candidates are rapidly evaluated using native multi-physics simulation capabilities, and a variety of design exploration and optimization techniques in 3DEXPERIENCE automate the evaluation of design feasibility and robustness. This enables a thorough exploration of product design alternatives, resulting in increased confidence in product performance, robustness, and quality while mitigating risks.

Fullwave Simulation and Analysis of Portable Transmitter Immunity Testing
Performing virtual prototyping to understand and solve EMC problems is becoming a norm in a typical product cycle. There are various forms of EMC simulations that can be performed. Of the many types, immunity simulation is one the most beneficial as the results obtained through measurements are difficult and almost impossible to quantify due to potential risks of equipment damage and human safety concerns associated with it.
In this presentation, 3D EM simulation is applied to model and analyze the impact of the field coupling to the DUT. Systematic analysis through gradual inclusion and impact of each individual component, such as the mobile transmitter antenna, PCB, TFT display, and metallic housing will be discussed. Through the use of 2D field plots and 3D field animations, it was possible to focus on the root cause of the problem. Having identified the source, virtual prototyping was applied to improve the robustness of the design.

Practical Simulation of Wave-structural Response of a Novel Gravity-Based Offshore Platform Using a Coupled FSI Analysis
Worley’s team has had the opportunity to design a unique, novel gravity-based offshore platform in the Caspian Sea. The platform’s substructure is a four-legged semi-submersible intended to sit on the seabed while withstanding harsh environmental loadings of the region. As one of the first platforms of its type, the design process is met with challenges that requires solutions outside of the design code conventions. The hydrodynamic load is a key design component that is addressed typically using Morison’s Equation for slender structures. Yet, the geometry of the substructure falls outside of the equation’s validity range, and thus requires an alternative, more detailed approach. The power of SIMULIA’s XFlow enables a coupled fluid-structure interaction analysis that address the need for hydrodynamic loading. The mapped hydrodynamic pressure represents a realistic wave actions, and when combined with the ice actions and soil-structure interaction modelled in Abaqus, they enable the design team to achieve robust and optimum design even for concepts that is outside of the industry standards.
