SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - The A Posteriori E
rror Estimation for Finite Element Method of the H(curl)-elliptic Problem
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
The A Posteriori Error Estimation for Finite Element Method of the H(curl
)-elliptic Problem\nSpeaker: Shuhao Cao\, Pennsylvania State University\nA
bstract: The coercive H(curl) problem\, sometimes named as H(curl)-ellipti
c\nproblem\, arises from the implicit time discretization of the\nsecond-o
rder hyperbolic initial boundary value problem for the\nelectric field. Bo
th the finite element discretization and its a\nposteriori error estimatio
n are discussed. The residual-based error\nestimator\, and several recover
y-based error estimators are constructed\nand analyzed.

on of magnetic field. A stable finite element discretization will be intro
duced\, so is a uniform solver for this discretization. Numerical results
are provided to verify the structure-preserving property and demonstrate t

SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - Numerical Study of
Geometric Multigrid Methods on CPU-GPU Heterogenous Computers
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
Numerical Study of Geometric Multigrid Methods on CPU-GPU Heterogenous Co
mputers\nSpeaker: Chunsheng Feng\, Xiangtan University\nAbstract: The geom
etric multigrid method (GMG) is one of the most efficient solution techniq
ues for\ndiscrete algebraic systems arising in many types of partial diffe
rential equations. GMG utilizes\na hierarchy of grids and discretizations
and reduces error of different frequencies simultaneously.\nGraphics proce
ssing units (GPUs) have recently burst onto the scientific computing scene
as a\ntechnology that has demonstrated substantial performance and energy
efficiency improvements.\nHowever GPU is not particularly efficient to co
arse level problems in GMG. In this work\, we\nstudy the performance of GM
G on CPU-GPU heterogenous computers. Furthermore\, for comparison\,\nwe co
mpare our method with an efficient implementation on CPUs as well as the F
ast\nFourier Transform in CuFFT.

SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - A Second Order Tim
e Homogenized Model for Sediment Transport
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
A Second Order Time Homogenized Model for Sediment Transport\nSpeaker: Sh
uonan Wu\nAbstract: A multi-scale method for the hyperbolic systems govern
ing sediment\ntransport in subcritical case is developed. The scale separa
tion of\nthis problem is due to the fact that the sediment transport is mu
ch\nslower than flow velocity. We first derive a zeroth-order homogenized
\nmodel\, and then propose a first-order correction. It is revealed that\n
that the first-order correction for hyperbolic systems has to be\napplied
on the characteristic speed of slow variables. We develop a\nsecond-order
numerical scheme following the framework of heterogeneous\nmulti-scale met
hod. The numerical results in both one and two\ndimensional cases demonstr
ate the effectiveness and efficiency of our\nmethod.

SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - High Order Nitsche
Extended FEM for Solving Interface Problem
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
High Order Nitsche Extended FEM for Solving Interface Problem\nSpeaker: F
ei Wang\, Penn State\nAbstract: Multi-physics problems is an very active r
esearch field recently. The most difficult part is how to couple different
systems\, which means that we have to deal with the interface\, which sep
arates two phases of matter\, each may be solid\, liquid\, or gaseous. The
standard finite element cannot achieve the optimal convergence order due
to lack of resolution for the interface. The interface-fitted mesh can con
quer this difficulty\, but if the problem is time-dependent\, the domain n
eed to be re-meshed each time step\, which introduces interpolation error
between two meshes. The extended finite element method (XFEM)\, which exte
nds the classical finite element method by enriching the solution space lo
cally around the interface with discontinuous functions\, has shown its po
tential in a variety of applications that involve non-smooth solutions nea
r interface. In this talk\, we will discuss about using quadratic XFEM wit
h Nitsche scheme to solve elliptic interface problem\, and try to prove th
e optimal convergence order.

SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - Fractional Sturm-L
iouville Eigen-Problems: Theory and Applications to Fractional PDEs in Hig
h Dimensions
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
Fractional Sturm-Liouville Eigen-Problems: Theory and Applications to Fra
ctional PDEs in High Dimensions\nSpeaker: Mohsen Zayernouri\, Brown Univer
sity\nAbstract: Fractional Calculus is unifying theory that generalizes th
e standard (integer-order) calculus to real (fractional-order) differentia
tion and integration. The corresponding non-local operators of fractional
order (in time and/or space) are shown to appear in a wide rang of applic
ations. In continuum-time random walk (CTRW)\, which allows to incorporate
waiting times and/or non-Gaussian jump distributions\, the continuous lim
it leads to the notion of fractional calculus yielding fractional in time
and/or space diffusion equation\, governing the PDF of the Levy processes.
In Bioengineering\, there is an extensive amount of experimental evidence
that highlights such processes occur in critical applications such as dif
fusion processes in human brain\, cardiac tissue electrode interface\, vis
coelastic response of human red-blood-cells\, wall-arteries\, lung tissues
\, etc. In such power-law attributed phenomena\, fractional PDEs naturally
appear as the right mathematical framework. extension of existing numrica
l methods to FPDEs is not trivial because of their non-local and history-d
ependent nature. To this end\, we first present a fractional (regular and
singular) Sturm-Liouville eigen-problems\, recently developed by Zayernour
i & Karniadakis JCP 2013\, which serves as a fundamental theory that provi
des explicit (non-polynomial) eigen-functions\, namely as Jacobi Poly-frac
tonomials. These eigen-functions extend the well-known family of Jacobi po
lynomials to their fractional counterparts\, where we show that they enjoy
many attractive properties such as orthogonality\, recurrence relations\,
exact fractional derivatives/integrations\, in addition to their spectral
properties. Based upon this base fractional theory\, we develop a unified
Petrov-Galerkin spectral method for solving the whole family of parabolic
\, elliptic\, and hyperbolic (time- and space-) fractional PDEs in any (d+
1)-dimensions in a hypercube. While the existing numerical methods can tak
e days to run a One-Dimensional problem\, we also formulate a unified fast
linear solver for our scheme\, which allows one to run a "Ten-Dimensional
" FPDE on a laptop within a fractional of an hour!
