FORTRAN Unit Test Framework FRUIT - TDD in FORTRAN
FORTRAN Unit Test Framework, written in FORTRAN 95. So that all FORTRAN features can be tested. FRUIT has assertion, fixture, setup, teardown, report, spec, driver generation. Rake used as build tool. Tutorials at http://fortranxunit.wiki.sourceforge.net The core testing part is in FORTRAN, this part can be used independent of the Ruby codes. The Ruby code is to make fixtures and reports easier. Rake is to build the project elegantly. This project also demonstrate a new way to build mixed language code in an alternative way than Make. Most of the FORTRAN are important in nature, used in nuclear and aerospace codes, etc, and maintained and written actively. Please help to bring TDD practices to the FORTRAN community. The change could be very hard, personally, I quit, since I could not make the change. I hope your organization will be successful. Enjoy a cup of fruit while maintaining FORTRAN ! Andrew Hang Chen and other maintainers who feel importance of TDD in cr
Generic data-assimilation toolbox written in java, with native (c and fortran) libraries for high performance computing. Provides tools to couple to your own model and a wide range of algorithms, ranging from parameter calibration to Kalman filters.
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.
Airfoil optimization with Xfoil
Airfoil optimization using the highly-regarded Xfoil engine for aerodynamic calculations. Starting with a seed airfoil, Xoptfoil uses particle swarm, genetic algorithm and direct search methodologies to perturb the geometry and maximize performance. The user selects a number of operating points over which to optimize, desired constraints, and the optimizer does the rest.
