SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - Finite element met

DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
Finite element methods for stationary elliptic interface problems\nSpeake
r: Sanchez Uribe\, Manuel\, Brown University\nAbstract: In this talk we wi
ll present and discuss novel finite element methods for stationary ellipti
c interface problems\, using discretizations independent of the interface
(unfitted meshes). Our work is motivated by well known numerical methods:
Immersed Boundary Methods\, Immersed Interface Methods\, and Nitsche's met
hods. We will discuss these different directions. We prove optimal error e
stimates for our finite element methods\, independent of the diffusion coe
fficients. Finally\, numerical examples illustrating the performance of ou
r methods are presented corroborating our theoretical findings.

DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
Numerical Modeling of Ice Sheets\nSpeaker: David Pollard\, Pennsylvania S
tate University\nAbstract: A brief overview of continental-sized ice sheet
s will be given\, both for today (Greenland and Antarctica) and the past (
North American and Eurasian). Basic physical processes and the equations d
escribing ice-sheet variations through time will be described. The numeric
al techniques used to solve for the slow flow of ice deforming under its o
wn weight will be outlined\, focusing on the sparse-matrix solution of the
horizontal stretching equations. The performance of the sparse-matrix sol
ver used in our model will be assessed\, and advice sought on how to impro
ve on this performance.

city
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
A Robust Overlapping Schwarz Method for a Class of Hybridized Mixed Discr
etization of Elasticity\nSpeaker: Shihua Gong\, Peking University\nAbstrac
t: In this talk\, we will first present a family of new mixed finite eleme
nt methods for linear elasticity. The methods can be efficiently implement
ed by hybridization. In order words\, by introducing the Lagrange multipli
er to impose interelement continuity for stress\, the solution of the orig
inal indefinite system can be locally recovered by the Lagrange multiplier
\, which is the solution of a symmetric semi-positive-definite (SSPD) syst
em. We then develop an overlapping Schwarz method to the SSPD system and
prove its uniform convergence with respect to both the mesh size and Poiss
on ratio. Numerical tests are presented to validate the theoretical result
s.

DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
Homotopy continuation methods for nonlinear PDEs and applications\nSpeake
r: Wenrui Hao\, Ohio State University\nAbstract: This talk will cover some
recent work on homotopy continuation methods to solve systems of nonline
ar partial differential equations (PDEs) arising from biology and physics.
This new approach\, which is used to compute multiple solutions and bifur
cation of nonlinear PDEs\, makes use of polynomial systems (with thousands
of variables) arising by discretization. Examples from hyperbolic systems
\, tumor growth models\, and a blood clotting model will be used to demons
trate the ideas.

SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - Hybrid Finite Elem
ent Methods for Elasticity Problems
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
Hybrid Finite Element Methods for Elasticity Problems\nSpeaker: Alexandre
Madureira\, Laboratório Nacional de Computação Científica-LNCC\nAbstr
act Link: http://www.lncc.br/~alm/\nAbstract: In this talk we discuss the
use of hybrid methods for multiscale partial differential equations\, in
particular concerning the development of a hybrid scheme to solve the line
ar elasticity system. The unknowns are the displacements and the boundary
tractions at each element. Starting from a primal hybrid formulation\, the
method has a domain decomposition flavor\, and the displacements can be d
iscontinuous\, with continuous tractions. A decomposition of the primal sp
ace allows the reformulation of the continuous problem as a coupled system
of elementwise equations\, and a global mixed system posed on the mesh sk
eleton. The scheme is embarrassingly parallel\, where the local problems a
re solved independently. We shall discuss the connections between this and
some other methods.
