2016 Overset Grid Symposium Tutorials Schedule

The following tutorials on various overset tools and solvers are confirmed for Monday, October 17.

Introduction to SUGGAR++: Capabilities and Usage
Ralph Noack (Celeritas Simulation Technology, LLC)

Synopsis: An overview of the capabilities of Suggar++ will be given along with a brief introduction to the inputs and usage.

Integrated Overset Meshing and Assembly with Pointwise
Nick Wyman (Pointwise)

Synopsis: The hybrid mesh generator Pointwise, has been integrated with third-party overset assembly software to provide a unified environment for overset meshing. A tutorial will be provided for structured and unstructured overset mesh generation, assembly, and visualization.

Overset Mesh and Related Technologies in CFD++ from a User Perspective
Prasanth Kachgal and Sukumar Chakravarthy (Metacomp Technologies)

Synopsis: CFD++ is a powerful, general purpose CFD solver that is capable of solving complex flow problems with a high degree of accuracy, robustness, and efficiency. During this session, we will focus on showcasing the overset mesh and related technologies in CFD++ through the step-by-step setup and computation of several illustrative problems. By the end of this session, the audience should have insight into the versatility of the CFD++ solver, in particular with overset mesh and related applications, while also getting a feel for its ease-of-use.

Get the Most Out of Tecplot 360 EX with Overset Grids: Best Practices and Upcoming Features
Scott Imlay and Scott Fowler (Tecplot Inc)

Synopsis: The Tecplot Tutorial will give an introduction to visualization and analysis of CFD datasets using Tecplot 360 EX and Tecplot Chorus. The tutorial will cover:

Introduction to Overset Mesh with STAR-CCM+
Colin Heye (CD-Adapco)

Synopsis: This tutorial will introduce the overset mesh capabilities in CD-adapco’s STAR-CCM+ software. Participants will learn how to perform the entire CFD analysis process - including CAD preparation, meshing, solving, and post-processing – within STAR-CCM+. Because it is implemented in a widely used commercial package, STAR-CCM+’s overset mesh is compatible from incompressible to hypersonic flow regimes, and with various multiphase models like VOF, Lagrangian multiphase, and liquid films. Benefits of the unique overset capabilities, which include arbitrary unstructured mesh topologies and completely automatic hole-cutting and grid assembly, will be shown via step-by-step instructions on relevant cases.

Pegasus 5: Tutorial and "Tips & Tricks"
Stuart Rogers (NASA Ames Research Center)

Synopsis: This tutorial will provide an overview of the Pegasus5 software suitable for both novice and experienced users. The goal of the course will be to provide users with enough knowledge about the software that they may use it successfully for very complex systems of overset grids. The first part of the course will discuss the features of the software, and how these features attempt to automate the oversetting process. These include the automatic hole cutting and domain decomposition, the interpolation process, the optimization of overlap between grids, the automatic projection of overlapping surfaces, the restarting capability of the code, and the parallel-processing ability of the software. The second part of the course will provide an overview of the usage of the software. This will include a description of the required input files, the expected output files, and what the user should look for when they run the software. Profiling and understanding the parallel performance will be illustrated. The class will conclude with a discussion of overcoming problems when they arise, illustration of several examples, highlighting the newest features in version 5.2, and touch on new features that are under development.

OVERFLOW Tutorial: Best Practices and Grid Adaptation
Joseph Derlaga (NASA Langley), Thomas Pulliam (NASA Ames), and Pieter Buning (NASA Langley)

Synopsis: This OVERFLOW tutorial will be split into two parts. The first hour will focus on tips, tricks, and best practices in setting up and running OVERFLOW simulations. Topics will include gridding strategies, testing grid overlap, setup for moving body problems, and post-processing. The second hour will concentrate on near-body and off-body solution-adaptive gridding in OVERFLOW. The approach to grid adaption, user controls, and examples will be described. The intent is to allow users to test this new capability on their own problems.

Tutorial for Chimera Grid Tools
William M. Chan and Shishir A. Pandya (NASA Ames Research Center)

Synopsis: This tutorial will begin with an overview of the various pre- and post-processing modules in the Chimera Grid Tools (CGT) software package, followed by a brief status update on the Chimera Components Connectivity Program (C3P) for domain connectivity. A software demonstration of the graphical user interface OVERGRID, and the line-loads integration tool TRILOAD will be given. An introduction to grid generation script development using the CGT Script Library will be presented using the High-Lift CRM and a generic rocket as examples.

An Overture Tutorial
Bill Henshaw (Rensselaer Polytechnic Institute)

Synopsis: The Overture tutorial will give a introduction to constructing grids and solving partial differential equations using Overture. The tutorial will cover:

Overture is available free for download at www.overtureFramework.org.
