► 45th NIA CFD Seminar: Walsh Functions in Numerical Simulation: A New Framework for Solving Nonlinear Systems of PDEs
    8 Apr, 2014 

45th NIA CFD Seminar

Topic: Walsh Functions in Numerical Simulation: A New Framework for Solving Nonlinear Systems of PDEs

Date: Tuesday, April 22, 2014

Time: 11:00am-noon (EST)

Room: NIA, Rm141

Speaker: Peter Gnoffo

Speaker Bio: Dr. Peter Gnoffo is Senior Computational Aerothermodynamicist at NASA Langley Research Center. He earned his Ph.D in Mechanical and Aerospace Engineering at Princeton University in 1983. He joined NASA in 1974 after receiving a B.S. in Aerospace Engineering from Polytechnic Institute of Brooklyn. The subject lecture follows recent work published in the Journal of Computational Physics, Vol 258, pp 650-688, Feb 2014, titled ‘Global Series Solutions of Nonlinear Differential Equations with Shocks Using Walsh Functions.’

Abstract: A segmented, orthonormal basis function set composed of Walsh Functions is used for deriving global solutions (valid over the entire domain) to nonlinear differential equations that include discontinuities. A powerful, self-mapping characteristic of this set is closure under multiplication — the product of any two elements of the set is also an element of the set: gn(x) gm(x) = gk(x) (xb – xa)^{-1/2}. In the same way that Fourier series are used to generate global solutions to linear problems, this self-mapping property under multiplication allows similar approaches to non-linear problems. A new derivation of the basis functions applies a fractal-like algorithm (infinitely self-similar) focused on the distribution of segment lengths. Only two segment lengths are allowed in a group p. A recursive-folding algorithm that propagates fundamental symmetries to successive functions in the series determines the distribution of segment lengths. Functions, including those with discontinuities, may be represented on the domain as a series in gn(x) with no occurrence of a Gibbs phenomenon (ringing) across the discontinuity. Integrals and derivatives are computed using simple matrix multiplication of series representations of functions without the need for divided differences. A FORTRAN module for supporting Walsh function simulations is discussed. Examples are discussed for solution of the time dependent problems: an advection equation, a Burgers equation, and a Riemann problem.

► Webinar to Feature Supersonic Aircraft Design with Pointwise and SU2
    8 Apr, 2014 

FORT WORTH, TX (8 April 2014)—Pointwise will host a joint webinar on 29 April with Stanford University, Department of Aeronautics and Astronautics entitled “Supersonic Aircraft Shape Design Powered by SU2 and Pointwise.” The webinar, at 11 a.m. CDT (GMT -5), details how Pointwise and the open-source SU2 computational fluid dynamics (CFD) solver can be used to tackle supersonic aircraft design.

The webinar will be hosted by Travis Carrigan, Pointwise senior engineer; Thomas D. Economon, Trent Lukaczyk and Dr. Francisco Palacios of Stanford. Their biographies are available at www.pointwise.com/webinar.

To register, go to www.pointwise.com/webinar.

The webinar will demonstrate how to formulate and solve a shape design problem in SU2, using a continuous adjoint formulation to obtain the sensitivities for gradient-based optimization. Recent advances in simulation-based design opens doors to new supersonic aircraft designs with reduced sonic boom impacts, an important advance because current regulations do not permit supersonic flight over land due to sonic boom noise. The design of these aircraft requires accurate predictions of sonic boom on the ground and techniques for shaping the aircraft to achieve a desired boom signature while maintaining performance.

Watertight, surface and volume meshes for complex geometries can be quickly generated in Pointwise and exported to the native SU2 format. A properly constructed mesh aids in accurately predicting boom on the ground. A new script for Pointwise helps designers generate free-form deformation boxes for geometry parameterization and shape design in SU2.

The webinar will include a discussion of proper settings for the flow and adjoint problems, objectives and constraints, free form deformation design variables and mesh deformation. Optimal shape design results from SU2 for the Lockheed Martin 1021 aircraft from the 1st AIAA Sonic Boom Prediction Workshop will be presented.

Pointwise, Inc. is solving the top problem facing engineering analysts today – mesh generation for computational fluid dynamics (CFD). The company’s Pointwise software generates structured, unstructured and hybrid meshes; interfaces with CFD solvers, such as ANSYS FLUENT, STAR-CCM+, ANSYS CFX and OpenFOAM 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.
