SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - Numerical methods
for fine-scale petroleum reservoir simulation
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
Numerical methods for fine-scale petroleum reservoir simulation\nSpeaker:
Chensong Zhang\, Chinese Academy of Sciences\nAbstract: Computer simulati
on is widely used by petroleum engineers to understand oil recovery mechan
isms. We will first briefly review a few mathematical models for petroleum
reservoir simulation. Then we focus on a general compositional model and
develop a fully-implicit method as well as effective preconditioners for s
olving the Jacobian systems. We will also discuss efficient parallel imple
mentation of the proposed preconditioners on different platforms. The accu
racy\, robustness\, and parallel scalability of the parallel simulator are
then validated using large-scale black oil benchmark problems.

DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
An introduction of the Allen-Cahn equation and the Cahn-Hilliard equation
\nSpeaker: Yukun Li\, Penn State University\nAbstract: First we will brief
ly talk about the background in material science\, then we will show the r
elation between these two equations and geometric problems. We will focus
on the Cahn-Hilliard equation\, and introduce some well-known facts\, incl
uding existing PDE and numerical results. Besides\, we will discuss the sp
ectrum estimates\, which play important roles in analyzing the asymptotic
behavior of the solution of the Cahn-Hilliard equation. Finally\, some num
erical tests are given to verify the evolution of the solution\, which is
consistent with the corresponding geometric law.

SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - High Order Extende
d Finite Element Methods with Discontinuous Galerkin Schemes for Solving I
nterface Problems
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
High Order Extended Finite Element Methods with Discontinuous Galerkin Sc
hemes for Solving Interface Problems\nSpeaker: Yuanming Xiao\, Nanjing Uni
versity\nAbstract: Two different discontinuous Galerkin (DG) schemes on ar
bitrary order extended finite element (XFE) spaces are proposed for solvin
g elliptic interface problems. Non-standard trace and inverse inequalities
on curved sub-elements are derived to guarantee the stability of the bili
near forms. Optimal error estimates in broken $H^1$ norm\, as well as in $
L^2$ norm\, are thus obtained. In particular\, we have devised a parameter
-friendly DG method\, which means no ``sufficiently large'' parameters are
needed to ensure the optimal convergence of the scheme. All the estimates
are independent of the location of the interface relative to the meshes.

DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
Numerical Analysis and Computations of Fluid Flows: Geophysical Flows and
Classical Flows\nSpeaker: Arthur Bousquet\, Penn State University\nAbstra
ct: Computations of fluid flows using finite volume methods with and witho
ut multilevel methods. Multilevel methods use incremental unknowns\, which
were originally developed for the study of turbulent flows\, I adapt thes
e. There are two types of multilevel methods: the average finite volume mu
ltilevel method (AFVM) and the hierarchical finite volume multilevel metho
d (HFVM). Then\, I will present an application of the HFVM to the two dime
nsional shallow water equations using the Central-Upwind Scheme (CUS). I a
lso present a Finite Volume discretization of the two-dimensional inviscid
primitive equations in a domain with topography. For these equations\, I
compare the so-called Upwind Scheme (US) and the Central-Upwind Scheme (CU
S). Last\, I will introduce the equation of elasticity for virus deformati
ons.

SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - Mixed finite eleme
nts of any order in any dimension for linear elasticity with strongly symm
etric stress tensor
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
Mixed finite elements of any order in any dimension for linear elasticity
with strongly symmetric stress tensor\nSpeaker: Shuonan Wu\, Penn State U
niversity\nAbstract: We propose two classes of mixed finite elements for l
inear elasticity of any order\, with interior penalty for nonconforming sy
mmetric stress approximation. One key point of our method is to introduce
some appropriate nonconforming face-bubble spaces based on the local decom
position of discrete symmetric tensors\, with which the stability can be e
asily established. We prove the optimal error estimate for both displaceme
nt and stress by adding an interior penalty term. The elements are easy to
be implemented thanks to the explicit formulations of its basis functions
. Moreover\, the method can be applied to arbitrary simplicial grids for a
ny spatial dimension in a unified fashion. Numerical tests for both 2D and
3D are provided to validate our theoretical results.

Determining continuum quantities from Molecular dynamics models\nSpeaker:
Xiaojie Wu\, Penn State University\nAbstract: Even though Molecular dynam
ics (MD) models continuum mechanics are\nwidely used in the same areas\, t
he connection between MD models and\ncontinuum mechanics is not clear. Thi
s talk will review the definition\nof virial stress and Hardy's theory. Mo
re generalized definitions of\ncontinuum quantities will be presented in b
oth Eulerian and Lagrangian\nspecification. Some techniques are also invol
ved to improve the\naccuracies of these quantities. The techniques are ver
ified by\nnumerical simulations. This talk will end up with the definition
of\ntraction for many-body potentials.

SUMMARY:CCMA PDEs and Numerical Methods Seminar Series - Efficient spectral
methods on PDE in spherical domain
DESCRIPTION:Seminar: CCMA PDEs and Numerical Methods Seminar Series\nTitle:
Efficient spectral methods on PDE in spherical domain\nSpeaker: Lina Ma\,
Penn State University\nAbstract: Many mathematical models are related to
spherical domains. Most common examples would be the Earth\, and other ast
rophysical bodies as the Sun. The model discussed in this talk is a reduce
d MHD model for the sun and a exterior problem of time harmonic Maxwell Eq
uations. Scalar/vector Spherical harmonic functions are introduced in orde
r to cooperate with spherical coordinates. By performing spherical harmoni
c analysis\, we can turn global operators into local operators\, and reduc
e dimension of the problem\, in addition\, one can increase computational
efficiency and accuracy by applying the high-order spectral methods.
