Efficient upwind algorithms for solution of the Euler and Navier-stokes equations [PDF]
, 1995 An efficient three-dimensionasl tructured solver for the Euler and Navier-Stokese quations is developed based on a finite volume upwind algorithm using Roe fluxes. Multigrid and optimal smoothing multi-stage time stepping accelerate convergence.

Topics in Numerical Computation of Compressible Flow [PDF]
, 1990 This thesis aims to assist the development of a multiblock implicit Navier-Stokes code for hypersonic flow applications. There are mainly three topics, which concern the understanding of basic Riemann solvers, the implementing of implicit zonal ...

Composite Backward Differentiation Formula for the Bidomain Equations
Frontiers in Physiology, 2020 The bidomain equations have been widely used to model the electrical activity of cardiac tissue. While it is well-known that implicit methods have much better stability than explicit methods, implicit methods usually require the solution of a very large ...

Discretization of asymptotically stable homogeneous systems by explicit and implicit euler methods [PDF]
2016 IEEE 55th Conference on Decision and Control (CDC), 2016 Sufficient conditions for the existence and convergence to zero of numeric approximations to solutions of asymptotically stable homogeneous systems are obtained for the explicit and implicit Euler integration schemes. It is shown that the explicit Euler method has certain drawbacks for the global approximation of homogeneous systems with non-zero ...

The Lie group Euler methods of multibody system dynamics with holonomic constraints
Advances in Mechanical Engineering, 2018 The Euler methods on Lie group are developed for the differential–algebraic equations of multibody system dynamics with holonomic constraints. The implicit Euler method is used to solve the differential–algebraic equations as Euler–Lagrange equations on ...

Resolution of the implicit Euler scheme for the Navier–Stokes equation through a least-squares method [PDF]
Numerische Mathematik, 2021 The approach to solve the Navier-Stokes equations involving implicit time schemes introduced in [\textit{M. O. Bristeau} et al., Comput. Methods Appl. Mech. Eng. 17--18, 619--657 (1979; Zbl 0423.76047)] is analyzed using a least-squares method.

A linear implicit Euler method for the finite element discretization of a controlled stochastic heat equation [PDF]
IMA Journal of Numerical Analysis, 2021 AbstractWe consider a numerical approximation of a linear quadratic control problem constrained by the stochastic heat equation with nonhomogeneous Neumann boundary conditions. This involves a combination of distributed and boundary control, as well as both distributed and boundary noise.

Embedding wellformed Euler diagrams [PDF]
, 2008 Euler diagrams are collections of labelled closed curves. They are often used to represent information about the relationship between sets and, as such, they have numerous applications including: visualizing biological data, diagrammatic logics, and ...
