I am the maintainer of an unpolished finite-element like solver program relying on an underlying 'grid' data structure, where each grid cell has a certain 'temperature', and temperature flows between cells. The program, as written, relies on text-input files containing the dimensions and location of each grid cell. I'd like a GUI interface written for the program (preferably in Java) that allows the user to 'draw' these box diagrams in, that will generate the appropriate internal object, call the pre-written solver routines, then display the output values in a graphical fashion. The GUI input must support CAD-like input, where rects can be not only drawn by mouse-drags, but can also have their dimensions and location modified by either drop-downs or some other text means. The primary difficulty in this project (next to GUI creation) is the creation of this internal data object, which, if two overlapping boxes are drawn, must 'subdivide' the boxes into sub-rectangles. As such, the overlap of 2 rectangles can generate up to 5 resulting rectangles, depending on the type of overlap. This gets complicated when you have N total (and possibly overlapping) rectangles, resulting in a very large number of subrects.
## Deliverables
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Deliverables must be in ready-to-run condition, as follows? (depending on the nature? of the deliverables):) For all others including desktop software or software the buyer intends to distribute: A software? installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.
3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
## Platform
The FEM solver currently is written in C, and compiles on x86, Solaris, and Mac OS X. It requires the use of Math libraries, such as the Intel MKL, and Apple's Accelerate framework. I'd like to be able to use standard "make" to compile the final program.
