The following tutorials on various overset tools and solvers are planned for Monday, October 15:
Pointwise Tutorial (8:30am—10:00am)
Introduction to Overset Mesh within STAR-CCM+ (10:00am—11:30am)
Matt Janeway and Milovan Peric (CD-adapco)
This tutorial will introduce the unstructured overset mesh capabilities in STAR-CCM+, and the procedures for a successful simulation. The entire process, including CAD preparation, meshing, solving, and post-processing - all within the STAR-CCM+ environment - will be demonstrated. Finally, an overview of the CAD-to-Solution capabilities of STAR-CCM+ will be given.
Introduction to OpenFOAM (12:30pm—2:30pm)
Eric Paterson (Virginia Tech University)
Using CFD++ with Overset Composite Grids (2:30pm—4:00pm)
Prasanth Kachgal and Sukumar Chakravarthy (Metacomp Technologies)
Synopsis: The tutorial will go over what the user will see and do in the CFD++ user interface to work with overset composite grids. A typical problem will be set up and run using the demo laptop. Besides the practical demonstration, a detailed overview of the related capabilities available in Metacomp's software suite which includes CFD++, CAA++, CSM++ and MIME will be presented.
Tips & Tricks for post-processing OVERFLOW Results with FieldView 13 (4:00pm—5:30pm)
Earl P. Duque (Intelligent Light)
Synopsis: As an OVERFLOW and FieldView user for several years, I'd like to share with you several methods I've used for getting my work done in a more efficient manner. With the most recent version, FieldView 13, you'll find new features and workflows that will benefit your work. From reading your data more completely using the new OVERFLOW direct reader to using our XDB technology to reduce your saved data, I'm sure you may find that at least one of the "Tips and Tricks" contained in this talk will be useful to your daily work.
A Chimera Grid Tools Tutorial (8:30—10:00am)
William M. Chan and Shishir Pandya (NASA Ames Research Center)
Synopsis: A brief overview of the capabilities of Chimera Grid Tools (CGT) will be given. These include pre-processing tools for geometry/grid manipulation and generation, flow solver input preparation, and various post-processing tools for aerodynamic loads computation, convergence analysis, and solution visualization. A step-by-step demonstration will be presented on how to create a pre-processing script using OVERGRID and the CGT Script Library from typical geometry inputs. The pre-processing script will cover parameterized grid generation steps, and inputs preparation for domain connectivity, flow solver, and aerodynamic loads computation. Finally, a short demonstration will be given on the line loads computation tool TRILOAD.
Pegasus 5: An Automated Pre-Processor for Overset-Grid CFD (10:00am—11:30am)
Stuart Rogers (NASA Ames Research Center)
Synopsis: This 90 minute 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. The class will conclude with advice on overcoming problems when they arise, and illustration of several examples.
OVERFLOW Discussion (11:30—12:00pm)
Pieter Buning (NASA Langley Research Center)
Synopsis: This will provide a summary of recent features added to the OVERFLOW flow solver, a description of how to request the code from NASA, and a question-and-answer period.
SUGGAR++ Tutorial (2:30pm—4:00pm)
Ralph Noack (The Pennsylvania State University)
An Overture Tutorial (4:00—5:30pm)
Jeff Banks, Kyle Chand, Bill Henshaw (Lawrence Livermore National Lab)
Synopsis: The Overture tutorial will give a introduction to constructing grids and solving partial differential equations using Overture. The tutorial will cover (1) solving an advection-diffusion equation using the high-level C++ interface (one of the Overture primer examples), (2) creating mappings (component grids) with Overture geometry tools and constructing overlapping grids with Ogen, (3) solving incompressible flows with Cgins (including moving grids) and (4) solving compressible flows with Cgcns (including the use of adaptive mesh refinement). Instructions for downloading and installing Overture on your own machine in order to run the software during the tutorial session may be found here.
