Short Course/Training
There will be four short courses offered on October 13, 2008. Click on the name of the course to learn more about its content.
Short Course #1: Overflow Class
Short Course #2: An Introduction to Suggar++
Short Course #3: An Overture Tutorial: An Introduction to
Grid Generation and PDE Solvers
Short Course #4: Overset Grid Generation Using OVERGRID
and the Chimera Grid Tools Script Library
Short Course #1: Overflow Class
An eight-hour course
Instructors: Pieter Buning (NASA/LaRC) and Bobby Nichols (UAB)
Synopsis: The objective of this class is to provide the CFD practitioner with a working knowledge of the models and methods available in the latest release of the OVERFLOW 2.1 overset structured grid Navier-Stokes code. Both the flow solver and the moving grid capabilities contained in OVERFLOW 2.1 will be discussed. Emphasis will be given to recent upgrades to the software. The OVERFLOW 2.1 software is ITAR restricted. The code is available to the U. S. government and industry and is distributed by NASA.
Proposed Outline:
- Beginner's Guide (I've got my grid, now what?)
- What to do with all those options?
- Turbulence model
- Right-hand side
- Left-hand side
- Boundary conditions
- Time-Accuracy (and Low-Mach Preconditioning)
- How to run
- Unsteady data extraction
- Moving body problems
- Parallelization
- Hardware matters (but it will be different next year)
- MPI vs. OpenMP
- Convergence issues
Short Course #2: An Introduction to Suggar++
Space is limited
A four-hour course
Instructors: Ralph Noack and David Boger (Penn State Applied Research Lab)
This short course will provide an introduction to the Suggar++ overset grid assembly tool. Suggar++ is a completely new code being developed from scratch to replace the capability provided by the existing Suggar code. A new hole cutting approach has been developed and will be presented along with various other details of the approach. Input parameters will be discussed and illustrated with example problems. If time permits a hands-on portion of the class will permit users to try Suggar++ on their own geometries. This will be a Beta release of the software with significant, but not full, functionality. Attendees should be familiar with the overset approach and hopefully have some experience with Pegasus5 or Suggar. Linux workstations with Suggar++ and Gviz installed will be used for the class.
Short Course #3: An Overture Tutorial: An Introduction to Grid Generation and PDE Solvers
Space is limited
A two-hour course
Instructors: Bill Henshaw and Kyle Chand
This course introduces the mesh generation tools and PDE solvers available from the Overture project. The first part of the course provides an overview of Overture as well as
some hands on experience with our interactive mesh generation tools. Tutorial attendees will learn how to build component and overlapping grids with "ogen"; we will also
demonstrate mesh generation from CAD data via IGES files. The tutorial's second half focuses on using some of the PDE solvers available from our project. Grids generated in the
first part of the class are used as input to the incompressible Navier-Stokes solver ("cgins"), compressible Navier-Stokes solver ("cgcns") and, time permitting, the multi-physics
solver ("cgmp"). LLNL-ABS-402685
Short Course #4: Overset Grid Generation Using OVERGRID and the Chimera Grid Tools Script Library
Space is limited
A two-hour course
Instructor: William M. Chan (NASA Ames Research Center)
This course will provide a brief introduction to the Chimera Grid Tools (CGT) software package. A quick demonstration of the basic features of the OVERGRID graphical interface will be
given, followed by highlights on more recent additions, including the CAPRI CAD interface. A demonstration of grid generation script development using the CGT script library will also
be given. If time permits, a sneak demo of the new OVERSMART post-processing tool will be shown.
