  • CFD Utilities Icon

    CFD Utilities

    CFD-related Fortran libraries and applications

    The CFD Utility Software Library (previously known as the Aerodynamics Division Software Library at NASA Ames Research Center) contains nearly 30 libraries of generalized subroutines and close to 100 applications built upon those libraries. These utilities have accumulated during four decades or so of software development in the aerospace field. All are written in Fortran 90 or FORTRAN 77 with potential reuse in mind. The only exception is the C translations of a dozen or so numerics routines grouped as C_utilities. David Saunders and Robert Kennelly are the primary authors, but miscellaneous contributions by others are gratefully acknowledged. See 1-line summaries of the libraries and applications under the Files menu. Each library folder also contains 1-line summaries of the grouped subroutines, while each application folder contains READMEs adapted from the main program headers. NASA permission to upload actual software was granted on Jan. 24, 2014.

  • Molecular Dynamics Studio

    Molecular Dynamics Cell Construction

    This is a collection of software modifications created to integrate NanoEngineer-1, PACKMOL and MSI2LMP for the purpose of easily creating molecular dynamics cells. NanoEngineer-1 is a molecular CAD software written by Nanorex and provides the user an easy way to create molecules, while the software modifications allow the user to type atoms using multiple force fields. PACKMOL can generate a random collection of molecules using the molecule templates from NanoEngineer-1 thus providing the initial MD cell. Modifications to PACKMOL allow the atom type data to be passed through to the MSI2LMP software. MSI2LMP creates a LAMMPS input file based on class I or class II force fields. MSI2LMP was modified to use numerically coded force field data generated by NanoEngineer-1. The MMP file format was extended and integrated into all three software applications.

  • NanoCap Icon


    Carbon Fullerene and Capped Nanotube Generator

    NanoCap is a generic application for the construction of low energy fullerene and capped nanotube structures. It provides an ideal tool to accompany the study of finite carbon molecules using computer simulation. The implementation involves a standalone application which includes a GUI and allows for dynamic visual inspection through 3D rendering. In addition, the NanoCap core libraries can be used in custom Python scripts that enabled the user to produce structures in bulk or to include the structure generation routines into pre-existing code.

  • Easy Beginner's Environment in QT

    This is a port of the ebe programming environment to QT.

    The ebe programming environment is a nice IDE designed for developing Assembly programs. It also handles C and C++ programs as well since there was not much extra effort. It used to support Fortran and this could return if people want Fortran. This project is an effort to recode ebe using C++ and QT. Originally ebe was coded using Python, Tkinter and Pmw, which worked out pretty well. The QT environment offers substantially better GUI controls. The most obvious difference is that Python ebe has a lot of separate windows, while the QT ebe will use 1 main window and a collection of dockable subwindows. This will make it easier to use.
