Dimensional Generator
Fortran code to perform dimensional analysis, by Ron Davis.
Double-Diffusive Convection Code Using a Pseudo-Spectral Method
Fortran 77 code illustrating the use of spectral methods to solve a nontrivial hydrodynamics problem.
DYNAMO
Library of Fortran 90 modules that has been designed for the simulation of molecular systems using molecular mechanical (MM) and hybrid quantum mechanical (QM)/MM potential energy functions.
Earth Tech: CALPUFF Codes and Related Processors
Codes to process geophysical and meteorological data.
ElectronicStructure.org
Links to electronic structure codes, many in Fortran.
EMLIB
Electromagnetic software in Fortran and C, and related information.
Eta
Weather forecasting code in Fortran 90. Source code can be requested from the site.
EXCITING FP-LAPW Code
Full-potential linearised augmented-planewave (FP-LAPW) Fortran 90 code. Written mainly at Karl-Franzens-Universität Graz as a milestone of the EXCITING EU Research and Training Network, the code is designed to be as developer friendly as possible so that new developments in the field of density functional theory (DFT) can be added quickly and reliably. The code is freely available under the GNU General Public License.
FGHEVEN
Solves the one-dimensional Schrodinger equation for bound state eigenvalues and eigenfunctions corresponding to a potential V(x).
Fortran 90 Massively Parallel Source Codes for the Cray T3E
Code for the Ising model by Gyorgy Korniss.
FreeSRS
Library of Fortran and Python code to calculate the shock response spectrum.
F77xml
C library designed to provide DOM parsing functionality to Fortran 77. It acts as a wrapper to gdome2 library.
Gastropod IR RT operator
Fortran 90 library of forward and gradient routines for fast radiative transfer calculations for high spectral resolution infrared satellite sounders.
General Software
Fortran and C programs for processing meteorological and oceanographic data from the Scientific Computing Division of the National Center for Atmospheric Research.
General Utility Lattice Program (GULP)
Performs a variety of types of simulation on 3D periodic solids, gas phase clusters and isolated defects in a bulk material. In particular GULP is designed to handle both molecular solids and ionic materials through the use of the shell model. One difference between GULP and other similar programs is that symmetry is used for solids to accelerate the calculations and to simplify the input. Freely available to academics only.
GeoFramework Code
SPECFEM3D_BASIN is a spectral-element package which simulates seismic wave propagation in sedimentary basins. SPECFEM3D_GLOBE is a spectral-element package which simulates global and regional seismic wave propagation. The packages are written in Fortran 90, conform strictly to the Fortran 95 standard, and use the Message Passing Interface (MPI).
Goddard Institute of Space Studies
Code for climate modeling, radiation, and astrophysics.
GS2
Fortran 90 code to study low-frequency turbulence in magnetized plasma.
HEAP
Fortran 90 and High Performance Fortran code implementing nonadaptive and adaptive O(N) hierarchical N-body methods in 3-D for gravitational and electrostatic fields.
Horizon Technologies
Code for properties of fluids, materials, and superconductors.
