CadenceLIVE Silicon Valley 2022 - CFD Track: Seven Reasons to Attend

Posted By: Anne-Marie Schelkens
Date:Fri, 20 May 2022, 4:36 p.m.

CadenceLIVE 2022 CFD Track

On June 8th and 9th, it is CadenceLIVE Silicon Valley. It is planned to be in-person at the Santa Clara Convention Center in California, and that is already your first important reason to join us! We are finally getting back to face-to-face networking, enjoying wonderful food and drinks, and seizing invaluable opportunities to discuss, learn and share ideas and opinions with colleagues, peers, industry thought leaders, and experts, all gathered in one place.

The CFD Track will be held on Wednesday the 8th, and that brings me to six more valuable reasons to attend:

1. A Disruptive CFD Technology Applied to Automotive Simulations — Olivier Thiry, Cadence

Cadence presents a new technology based on advanced numerical algorithms that yield high scale-resolving accuracy on low-cell-count grids within fast turnaround times. The solver is fully integrated into an end-to-end platform that streamlines the geometry preparation, mesh generation, simulation, and co-/post-processing, leveraging the power of GPU infrastructures with minimal user intervention.

2. Advanced Modeling of Hypersonic Reentry — Maximilian Maigler, UniBw Munich

We will present the approach, results, and validation of modeling hypersonic reacting flows, specifically the reentry of spacecraft into Earth, Mars, and Titan atmospheres using advanced computational fluid dynamics. The models include dissociation behind the shock wave in front of the vehicles as well as ablation effects on the thermal protection system. We compare fully and semi-structured meshing approaches and results obtained by commercial (Ansys Fluent) and Open Source software (OpenFOAM with community packages). The validation is carried out using experimental data and existing publications for specific flow problems such as test geometries and several experimental and in-operation vehicles.

3. High-Lift Common Research Model: RANS, HRLES, and WMLES Perspectives for CLmax Prediction — Cetin Kiris, NASA Ames Research Center We will present a unified assessment of three turbulence treatments: Reynolds Averaged Navier-Stokes (RANS), Hybrid RANS/LES (HRLES), and Equilibrium Wall-Modelled Large Eddy Simulation (WMLES) for the High-Lift Common Research Model (CRM-HL).

4. Output-Based Mesh Adaptation for Low and High Speed Aerospace Regimes — Dr. Marshall Galbraith, MIT (Massachusetts Institute of Technology)

Output-based mesh adaptation is achieved by coupling the MIT SANS finite-element solver and metric optimization with the Pointwise mesh generator. The interface between SANS and Pointwise is a fine-grain point cloud of sizing requests that drives the Pointwise meshing algorithm. Viscous adaptation is achieved via a hybrid approach where sizing requests drive isotropic refinement, and viscous layers are apriori generated. Adaptation results are shown for 2D inviscid and viscous airfoil cases starting from extremely coarse initial mesh resolution, as well as select 2D hypersonic test cases.

5. Realizing CFD Vision 2030: Progress and Future Plans within the Aerospace Community — Jeffrey Slotnick, Boeing

This presentation will focus on the activities of the AIAA-sponsored CFD2030 Integration Committee (IC), which has been established to promote and advance the objectives of the Vision study. These activities include a thorough review and update of the technology development milestones and demonstrations outlined on the roadmap, a focus on defining the details of critical CFD Grand Challenges, and efforts to engage the aerospace and CFD communities through AIAA-hosted conference events, such as Forum 360 panel discussions. Finally, related activities closely aligned with the CFD2030IC, including CFD validation and prediction workshops, as well as efforts to advance Certification by Analysis, will also be discussed.

6. Towards Wall-Resolved Large Eddy Simulation of the NASA CRM High-Lift Configuration: Preliminary Results — ZJ Wang, University of Kansas

Supported by DOE's INCITE program, we are performing a wall-resolved large eddy simulation (WRLES) of the NASA Common Research Model (CRM) high-Lift Configuration on Summit. Progresses in many areas are needed to enable this undertaking: adaptive high-order methods, high-order mesh generation, implicit solution algorithms, and efficient implementation on extreme scale CPU/GPU clusters. Preliminary results will be presented.

Moreover, at the booths in the exhibition hall, our engineers will be available to answer any of your questions, show you live demos, help with advice and tips & tricks, and much more.
