This software tool provides much information about the cases it solves: speed field, pressure field, speed divergence, drag and lift coefficients, contaminant transport, pressure and speed gradient figures, turbulence distribution, particle tracing, and so on. It is possible to define complex geometries due to unstructured meshes and a wide range of boundary conditions. ADFC uses a differential conjugated gradient and, when necessary, a turbulence model which can be Smagorinsky or K-epsilon. This code deals with calculation methods and problem solving, but other important processes such as geometry definition, meshing and postprocess must rely on other programs. ADFC is written in C++ and Java, and is released under the terms of the GNU General Public License. It runs on all 32-bit Windows 95/98/NT/2000/XP systems and all Linux/BSD/UNIX systems. The ability to read Spanish will be an advantage to users of this system. Ellipt2d - a finite element program for solving second order, real and complex, two-dimensional elliptic problems with user-defined operators.

Ellipt2d solves equations of the form: -div(F*grad(v)) + gv = s, where F (a tensor), g and s are user-supplied functions of x and y. The software is designed to be easily extendable, and is quick to write and understand because it's based on Python. Ellipt2d is distributed under the GNU General Public License. Full functionality requires Python 2.2 or later. In addition, if it is desired to build the shared libraries, a source version of Python and a C compiler are needed.

MMTL - the Multilayer Multiconductor Transmission Line 2-D and 2.5-D electromagnetic modeling - A suite of field solver programs, which convert dimensions and materials properties into electronic design parameters. The MMTL suite consists of several programs, including lossy, loss-free, quasi-static, and full-wave simulators. Circuit parameters are computed by either the method of moments (MOM) or finite element methods (FEM). Basic per-unit-length parameters are generated by the simulator, and can be converted into HSPICE W-element models. MMTL is similar in many ways to commercial field solver products which typically cost thousands of dollars. There are some free calculators, such as those from UltraCAD, but they rely on simplified formulas for specific cases, instead of generalized electromagnetic modeling. MMTL is implemented in C, C++, FORTRAN, sh, and Tcl/Tk, and has been deployed on HP-UX, Linux, Windows, Solaris, and Alpha/OSF1. Please visit the Sourceforge project page for details. MMTL programs and supporting libraries and documentation have been under development at the Mayo Clinic since the mid-1980s. The programs were developed under government sponsored electronics research programs in the Special Purpose Processor Development Group (SPPDG). They have been employed extensively at Mayo and distributed to some government agencies and research collaborators. The software is released under the GNU General Public License. Transcalc - Transmission Line Calculator - An analysis and synthesis tool for calculating the electrical and physical properties of different kinds of RF and microwave transmission lines. Transcalc is built using the GIMP toolkit (GTK+) for its GUI interface. Transcalc was influenced by Agilent Technologies' commercial program linecalc, but is intended to be more functional. Transcalc is built using the GIMP toolkit (GTK) for its GUI interface. Transcalc is written in C distributed pursuant to the GNU General Public License version 2 or (licensee's option) later.

FM is a component enabling the interchange of data that come in a variety of mesh and field types. It uses a general, extensible model for field data. FM is a follow-on project to the FEL2 project. A key objective of the project has been to develop a foundation set of classes for field data such that others can contribute code built on that foundation. FM is written in C++, and is a work in progress. It runs on Linux/BSD/UNIX systems, including IRIX. FLUXp - A Computational Aerodynamics/Fluid Dynamics package for solving compressible flow problems.

Current source is available by CVS, although only the downloads are supported. The CGNS system is designed to facilitate the exchange of data between sites and applications, and to help stabilize the archiving of aerodynamic data. The data are stored in a compact, binary format and are accessible through a complete and extensible library of functions. The API (Application Program Interface) is platform independent and can be easily implemented in C, C++, Fortran and Fortran90 applications. The CGNS project originated in 1994 as a joint effort between Boeing and NASA, and has since grown to include many other contributing organizations worldwide. The system is written in C and FORTRAN. It is distributed pursuant to the zlib/libpng License. OpenFOAM - Open Field Operation and Manipulation - A CFD Toolbox that can simulate complex fluid flows involving chemical reactions, turbulence and heat transfer. In addition, it is sufficiently general to be used for a broad range of problems in the physical sciences and engineering mechanics. It includes utilities to perform pre- and post-processing tasks ranging from simple data manipulations to visualisation and mesh processing. OpenFOAM is supplied with numerous pre-configured solvers, utilities and libraries and so can be used like any typical simulation package. However, it is open, not only in terms of source code, but also in its structure and hierarchical design, so that its solvers, utilities and libraries are fully extensible. It is written in C++ and Java and is distributed under the GNU General Public License. DUNS - Diagonalized Upwind Navier-Stokes code - A 2D/3D, structured, multi-block, multi-species, reacting, steady/unsteady, Navier Stokes fluid dynamics code with q-omega turbulence model. The DUNS code is a research code developed at the Propulsion Engineering Research Center at Penn State University in the mid to late 1990's. The object of the DUNS code was to make a CFD code both flexible and fairly general, and made great strides in that area compared with other codes I worked on while at Penn State, but it remains primarily a research code and does not have the same level of testing or validation that commercial codes have. We made it available on the internet at the request of some people because it can be applied to many different problems, but we were never able to devote the resources and manpower needed to make it truly user friendly and maintain it, or to do a complete set of validations to ensure that it runs correctly on a wide range of problems, especially for people who have little or no experience with CFD. It should certainly not be used as a replacement for commercial packages such as FLUENT, unless the people using it have considerable experience with CFD. The DUNS code has been developed using FORTRAN77 and C. It runs on Linux/BSD/UNIX systems, and is distributed pursuant to the GNU General Public License. The Gerris Flow Solver - Gerris - A tool for generic numerical simulations of flows (CFD), in geometrically complex geometries and including adaptive, multiphase and interfacial flows capabilities.

The code is suitable for Linux/BSD/UNIX platforms, including OS X, and is being actively developed. It is available persuant to the GNU General Public License OpenFlower - FLOW solvER - A C++ CFD code mainly intended to solve the turbulent incompressible Navier-Stokes equations with a LES approach.
