#### Local Atomic Temperature

(University of Texas at Arlington, 1989-10)

For the study of phase-transition by molecular dynamics, the concept of local temperature is desirable. Such a concept is defined and studied in this paper. From computer studies of tetrahedral arrangements of four atoms, ...

#### Supercomputer Simulation of Cracks and Fractures by Quasimolecular Dynamics

(University of Texas at Arlington, 1989)

The gross physical behavior of solids and liquids is the result of atomic or molecular reactions to external forces. Using molecular dynamics, we can study such reactions in the small, on the molecular level. In quasimolecular ...

#### Programs and Data Sets for Quasimolecular Modeling of Cavity Flow

(University of Texas at Arlington, 1987-01)

#### Rapid Computation of the Energy States of Two-Electron Atoms and Ions with an Explicit Formula for the Excited States of Helium

(University of Texas at Arlington, 1985-05)

A new computational approach is
developed for the energy states of
two electron atoms and ions. The
theory incorporates a classical
interpretation of electron pairing and requires Only simple numerical
methodology ...

#### Particle Simulation of Spiral Galaxy Evolution

(University of Texas at Arlington, 1985)

Spiral galaxies are modelled as n-body systems by means of long range and molecular-type short range forces. A relatively massive, elliptic, type core is sit into rotational motion in a less dense, tidal prone medium. ...

#### Rapid Computation of the Energy States of Two-Electron Systems

(University of Texas at Arlington, 1985)

A new deterministic approach to modelling atoms and molecules is developed which uses static and dynamic numerical methods. The estimate for the ground state energy of [see pdf for notation] is closer to the experimental ...

#### Pressure Method for the Numerical Solution of Transient, Compressible Fluid Flown

(University of Texas at Arlington, 1983-08)

In this paper the pressure method for incompressible fluid flow simulation is extended and applied to the numerical simulation of compressible fluid
flow. The governing equations, obtained from the physical principles ...

#### Particle Simulation of Compression Waves

(University of Texas at Arlington, 1984-05)

Compression waves are studied using a quasi-molecular, particle approach. Explosive type disturbances are simulated to generate such waves, which
propagate by the interaction of each particle with its immediate neighbors. ...

#### Particle Modeling of Unstable Mode Configurations and Elastic Bending of Deformable Shells

(University of Texas at Arlington, 1984)

A new particle-type of modeling is developed for the simulation of phenomena related to the bending of elastic shells. Application is
made to the determination of unstable equilibrium modes and to the simulation of ...

#### Local Molecular Temperature

(University of Texas at Arlington, 1989-11)

For the study of phase-transition by molecular dynamics, the concept of local temperature is desirable. Such a concept, defined and studied previously for atoms, is extended in this paper to molecules. The fundamental ...
