SCHEDULE: NOV 12-18, 2011

When viewing the Technical Program schedule, on the far righthand side is a column labeled "PLANNER." Use this planner to build your own schedule. Once you select an event and want to add it to your personal schedule, just click on the calendar icon of your choice (outlook calendar, ical calendar or google calendar) and that event will be stored there. As you select events in this manner, you will have your own schedule to guide you through the week.

You can also create your personal schedule on the SC11 app (Boopsie) on your smartphone. Simply select a session you want to attend and "add" it to your plan. Continue in this manner until you have created your own personal schedule. All your events will appear under "My Event Planner" on your smartphone.

Cardiovascular Hemodynamics Simulation including Time Dependent Deformational Forces

SESSION: George Michael Fellowship Presentation

EVENT TYPE: George Michael HPC Fellow Presentation

TIME: 10:30AM - 11:00AM

SESSION CHAIR: Mark Hoemmen

Presenter(s):Amanda Peters

ROOM:TCC LL4/LL5

ABSTRACT:
I will present a large-scale hemodynamics simulation. In this work, the Lattice Boltzmann method is used to model the flow in patient specific geometries derived from computed tomography angiography (CTA) data. I will provide here the derivation for introducing the deformational forces exerted on the arterial flows from the movement of the heart by borrowing concepts from cosmodynamics. Here I will discuss this method as well as provide an analysis of the impact of these additional forces on the endothelial shear stress, a quantity associated with the localization and progression of heart diseases like atherosclerosis, and the techniques leveraged to achieve excellent scaling on up to 294,912 processor cores.
