Efficient solution of 3D elasticity problems with smoothed aggregation algebraic multigrid and block arithmetics
Denis Demidov
Efficient solution of 3D elasticity problems is an important part of many industrial and scientific applications. Smoothed aggregation algebraic multigrid using rigid body modes fo…
Partial Reuse AMG Setup Cost Amortization Strategy for the Solution of Non-Steady State Problems
D. E. Demidov
The partial reuse algebraic multigrid (AMG) setup cost amortization strategy is presented for the solution of non-steady state problems. The transfer operators are reused from the…
Accelerating linear solvers for Stokes problems with C++ metaprogramming
Denis Demidov, Lin Mu, Bin Wang
The efficient solution of large sparse saddle point systems is very important in computational fluid mechanics. The discontinuous Galerkin finite element methods have become increa…
Thermoelectric properties of Wigner crystal in two-dimensional periodic potential
Mikhail Y. Zakharov, Denis Demidov, Dima L. Shepelyansky
We study numerically transport and thermoelectric properties of electrons placed in a two-dimensional (2D) periodic potential. Our results show that the transition from sliding to…
Wigner crystal diode
Mikhail Y. Zakharov, Denis Demidov, Dima L. Shepelyansky
We study the transport properties of a Wigner crystal in one- and two-dimensional asymmetric periodic potential. We show that the Aubry transition takes place above a certain criti…
AMGCL: an Efficient, Flexible, and Extensible Algebraic Multigrid Implementation
Denis Demidov
The paper presents AMGCL -- an opensource C++ library implementing the algebraic multigrid method (AMG) for solution of large sparse linear systems of equations, usually arising fr…
