FOR IMMEDIATE RELEASE
Pointwise, Suggar++ and Caelus Feature Overset Grid Generation
FORT WORTH, TX (18 November 2015) – Applied CCM Canada, Celeritas Simulation Technology and Pointwise will present a joint, 30 minute webinar entitled, “Overset Grid Generation and CFD using Pointwise, Suggar++, and Caelus” on 8 December at 10 a.m. CST (GMT -6).
The overset grid approach is a powerful technology that streamlines simulations that have complex geometries and/or regions in motion. Individual component grids are fitted to portions of the geometry without requiring point matching to other grids. Domain connectivity information (DCI) couples the overlap regions by providing interpolation sources and removing cells that are to be excluded from the computation. The DCI is computed by Suggar++, developed by Celeritas Simulation Technology. Suggar++ is a flexible, overset grid assembly (OGA) package available commercially worldwide.
While the benefits for dynamic grids are obvious, the overset approach can be advantageous for static grids as well because geometry changes require only local changes to the grid system. This flexibility simplifies design studies as new or perturbed geometry can easily be incorporated by only meshing the changed feature. Because the baseline grid system is not altered, changes in the solution are more reflective of the local geometry change rather global grid updates.
The process of generating overlapping grids, setting up and executing Suggar++, and exporting the DCI along with the grid system can all be accomplished within Pointwise. In this webinar, we will highlight several best practices for generating component grids and the procedure for setting up the necessary inputs for Suggar++. Finally, we will demonstrate an overset flow simulation using Caelus, a freely available fork of OpenFOAM® developed by Applied CCM.

Presenters will be Pointwise's Travis Carrigan, Pointwise, Inc.; Chris Sideroff, Ph.D., Applied CCM Canada; and Ralph Noack, Ph.D., Celeritas Simulation Technology, LLC.
Dr. Chris Sideroff has an extensive background in modeling a range of complex aerospace and turbomachinery flows and has led the planning, implementation, and support of several high-performance computing (HPC) clusters. He is the managing director and principle research engineer at Applied CCM Canada, a company providing development, technical support and training for open source based CFD software such as Caelus and OpenFOAM. Applied CCM Canada became a distributor of Pointwise beginning in 2015. Dr. Sideroff's current research interests are automation methods for CFD mesh generation, more robust discretization schemes for highly anisotropic and skewed meshes for finite volume based CFD solvers, work flow automation (pre, solve, post) with interpreted programming languages such as Python, and overset grid technologies. He earned his mechanical engineering B.Sc and M.Sc from the University of Alberta in Edmonton, Canada and Ph.D. degree from Syracuse University in Syracuse, USA.
Dr. Ralph Noack is the president of Celeritas Simulation Technology, LLC and the primary developer of Suggar++. He has been developing CFD solver, grid generation, and overset technology for 35 years. The last 15 years he has been developing Suggar++ and related software. He is now solely focused on developing and supporting Suggar++ and continuing to make it the premier overset capability in the world.
Pointwise, Inc. is solving the top problem facing computational fluid dynamics (CFD) today - reliably generating high-fidelity meshes. The company's Pointwise software generates structured, unstructured and hybrid meshes; interfaces with CFD solvers, such as ANSYS FLUENT, STAR-CCM+, ANSYS CFX, OpenFOAM, and SU2 as well as many neutral formats, such as CGNS; runs on Windows (Intel and AMD), Linux (Intel and AMD), and Mac, and has a scripting language, Glyph, that can automate CFD meshing. Large manufacturing firms and research organizations worldwide rely on Pointwise as their complete CFD preprocessing solution.
Applied CCM Pty Ltd and Applied CCM Canada support new and current users in the field of computational continuum mechanics by providing development, training and support and expanding the use of OpenFOAM®-based technologies in the academic and industrial communities. Applied CCM is also the originator and main developer of Caelus, a fork of OpenFOAM designed to improve the user experience and give businesses confidence that open-source CFD solutions are an excellent alternative to commercial offerings. Applied CCM are the distributors of Pointwise in the Oceania and Canadian regions and distributors of the industry leading overset grid assembly software, Suggar++, worldwide.
Celeritas Simulation Technology, LLC is a small company formed in 2010 with the purpose of continued development, distribution, and support of Suggar++: the premier general-purpose overset grid assembly software. Dr. Ralph Noack is the president of the company and lead software developer. He has over 20 years of experience in developing and using overset grid technology. Dr. Noack developed SUGGAR, which is similar but a less capable technology predecessor to Suggar++, and DiRTlib. DiRTlib is a software library that makes it easy to add an overset capability to a non-overset flow solver. Dr. Noack started development of Suggar++ in 2006 to overcome severe limitations in algorithms and software design of SUGGAR. He has been and continues to be the lead developer and architect of Suggar++.
