Kinematic wave computation using an efficient implicit method

Efficient Computation of Unsteady Viscous Flows by an Implicit Preconditioned Multigrid Method

An implicit preconditioned multigrid algorithm is developed for the efficient solution of two-dimensional, lowfrequency unsteady turbulent Navier-Stokes calculations on highly stretched meshes. The efficiency of the approach derives from three key attributes: 1) an implicit time discretization that allows the time step to be determined solely by the resolution requirements of the unsteady pheno...

Towards an efficient interval method for solving inverse kinematic problems

In this paper we present a new algehrwic analysis of the closure equation obtained for arbitrary single loop spatial kinematic chains, which allows us to design an eficient interval method for solving their inverse kinematics. The solution of a kinematic equation can be factored into a solution of both its rotational and its translational components. We have obtained general and simple expressi...

An Efficient Gvt Computation Using Snapshots

We describe, in this paper, a snapshot-based algorithm which makes use of distributed control. The algorithm is an extension of Mattern's snapshot algorithm and employs a leader election algorithm to pick a GVT ini-tiator. The leader election algorithm executes concurrently with the GVT algorithm. We prove the cor-rectness of the algorithm and compare its performance to several algorithms-Samad...

An efficient hybrid explicit/implicit solvent method for biomolecular simulations.

We present a new hybrid explicit/implicit solvent method for dynamics simulations of macromolecular systems. The method models explicitly the hydration of the solute by either a layer or sphere of water molecules, and the generalized Born (GB) theory is used to treat the bulk continuum solvent outside the explicit simulation volume. To reduce the computational cost, we implemented a multigrid m...
