ESTS0663 CFDLIB.

1. NAME OR DESIGNATION OF PROGRAM:  CFDLIB.

3. DESCRIPTION OF PROGRAM OR FUNCTION

CFDLib05 is the Los Alamos Computational Fluid Dynamics LIBrary. This is a collection of hydrocodes using a common data structure and a common numerical method, for problems ranging from single-field, incompressible flow, to multi-species, multi-field, compressible flow. The data structure is multi-block, with a so-called structured grid in each block. The numerical method is a Finite-Volume scheme employing a state vector that is fully cell-centered. This means that the integral form of the conversation laws is solved on the physical domain that is represented by a mesh of control volumes. The typical control volume is an arbitrary quadrilateral in 2D and an arbitrary hexahedron in 3D. The Finite-Volume scheme is for time-unsteady flow and remains well coupled by means of time and space centered fluxes; if a steady state solution is required, the problem is integrated forward in time until the user is satisfied that the state is stationary.

4. METHODS

Cells-centered Implicit Continuous-fluid Eularian (ICE) method.

7. UNUSUAL FEATURES

Handles either compressible or incompressible flow equations. The system allows the user to stipulate 2D or 3D as needed for the codes of interest. This version includes the possibility of auto-tasking in the SGI clusters, a new improved timstp routine and a new turbulence model. Many users have grid generators capable of output in the NASA Plot3d format. CFDLIB05 contains a translator for converting the Plot3d data into a form readable by CFDLIB05, and which generates some of the CFDLIB05 input data as well (see the directory/evtran in the library). For post-processing many users employ TecPlot, so the option exists to write a TecPLot-Formatted output file.
