Abstract: Simulation Based Design (SBD) Mesh Generation used in Automotive
Climate Control Applications
Simulation Based Design (SBD) is a specific type of CAE automation that enables one to apply CFD (thermal flow simulations) to 'real life' product development processes quickly and accurately. Innovative SBD methodologies to use CAD to author the shape of one's control volume and to use FluidConnection to author abstract CFD simulation models enable the speed. But, without an effective CFD solver and automatic mesh generator one will have speed but no accuracy in the simulation. The purpose of this presentation is to present what mesh techniques are currently available to generate appropriate automotive CFD (thermal
flow) simulations in a SBD paradigm and to discuss what gaps remain. In particular, the presentation will review the following meshing techniques and how they are used in automotive climate control applications:
1. isotropic surface meshing with curvature based refinement (size, curv, min_curv), 2. boundary layer meshing with limited blends and limited heuristics to deal with complex geometric interactions, 3. isotropic volume meshing with 2 to 1 transition, 4. enforce mesh size techniques to help in the transition from the boundary layer to isotropic volume meshing, 5. linear extrusion meshing.
Also, the presentation will discuss how the current SBD meshing process and desired meshing process is solver specific. In particular, how a FEA CFD solver and a finite volume CFD solver have different implicit mesh shape requirements. And as a result, what are future priorities for desired mesh techniques.
Mesh Requirements for Simulating the Unsteady Dynamics of General
N-Body problems are inherently unsteady and multi-disciplinary in nature. The problem class includes applications that involve any number of geometrically complex bodies in relative motion, flight/transport in close proximity with six-degrees-of-freedom, and the possibility of arbitrary inter-body collisions. Practical applications of this problem class exist in virtually every engineering discipline. The 15th IMR presentation on this topic will include several examples and technical discussion of associated meshing requirements.
An Abbreviated History of Sandia’s CUBIT Mesh Generation Project
The CUBIT mesh generation project has been in existence at Sandia National Laboratories since about 1992, with its precursors starting several years before that. During that time the CUBIT code has been used as a research sandbox, a development platform, and a production meshing application, often simultaneously. The project has played an important role in Sandia’s increased reliance on simulation-based design, and has been an integral part of Sandia’s participation in DOE’s Advanced Simulation Computing Initiative (ASCI) and Scientific Discovery for Advanced Computing (SciDAC) programs. This project has made an indelible mark on the meshing community, from its contribution of the patented Paving algorithm in 1990 to its continuing sponsorship of the International Meshing Roundtable.
