Presentation

Abstract

This talk will discuss recent advancements in the Helios code, the Army's high-fidelity CFD/CSD rotorcraft simulation code. These include a new implicit off body Cartesian solver to support both steady solutions and time-accurate RANS/DES in the wake, a new body hierarchy formulation to support coupled wing/rotor aeroelastics and maneuvering flight, a new strand-based near-body solver intended to support enhanced automation and accuracy, and the inclusion of two new unstructured near-body solvers—FUN3D from NASA and kCFD from the CREATE-AV Kestrel team. Also discussed will be new unsteady particle tracing and moving contour plane capability added to runtime-based in-situ visualization. Example application of these capabilities will be presented.

Biography

Andrew Wissink works for the US Army Aerodynamics Development Directorate located at NASA Ames Research Center. He has participated in the development of the Helios code since he joined the Army in 2006. Before that he worked at Lawrence Livermore National Lab from 1999-2006 and at NASA Ames from 1996-1999. He received his Ph.D. from the University of Minnesota in 1997.

Seminar Participation

Attending In Person

For select seminars, you may wish to attend in-person if you are in the vicinity of NASA Ames Research Center. These AMS seminars are held in Building N258 in Room 127, just off the front lobby. Sessions available to attend in-person will be indicated in the announcement information. In-person participants without NASA badges will need a valid visitor badge (US citizenship or permanent residency is required) to enter the facility.
