Research Interests

• Grid generation, flow solver, and solution analysis software and algorithm development for solving computational problems using Chimera overset grids
• Software optimization
• Graphical user interface development

Overset Grid Software

• The Chimera Grid Tools package contains a number of grid manipulation, grid generation, and solution analysis utilities. Some of the main modules include:
  • OVERGRID - Overset Grid Generation Graphical Interface for visualization of geometry/grids and for accessing the main grid modules
  • GRIDED - Grid Editor for structured grids
  • HYPGEN - Hyperbolic Field Grid Generator
  • PROGRD - Grid Projection Tool
  • SRAP - Spline, Redistribution and Projection tool for surfaces and curves
  • SURGRD - Hyperbolic and Algebraic Surface Grid Generator
  • TRIGED - Grid Editor for unstructured surface triangulations

• The FOMOCO Utilities package contains modules for flow coefficient computation and analysis on overset grids. The main modules are
  • MIXSUR - Hybrid surface grid generator for creating non-overlapping quadrilaterals and triangles from overset surface grids
  • OVERINT - Tool for computing pressure and viscous force, moment, and mass flow rate coefficients over hybrid surfaces created by MIXSUR; and for computing local force data on surface
  • OVERPLOT - Graphical interface for plotting residual and flow coefficient histories from output files created by the OVERFLOW flow solver. Section Cp plots can also be obtained on overlapping surfaces.
