Hi, I have written a piece of code to solve some simple heat transfer problems and to display the output also have written a simple contour plotting routine. The output could be better but because of the simplicity of my code I don't want to spend all my efforts developing the post-processing component.

Does anybody out there have, or know of, a 'free' contour plotting routine that I can drop into my program.

For reference my 'parent code' has been developed in an early version of MS Visual C++ and runs under MS Windows.

Thanks in advance.

(1). Try the commercial post-processor programs or the vendors. (2). The graphic program is much harder to write and it is usually much longer than the solver part.

Hello, Try Mathematica it can do it.

Hi .. I suggest you to spend more time and improve ur code... It will be good exercise for you...I will give a hint: "It is matter of interpolation to have the iso-lines".. If u gave up just contact me i have it in visual basic.. Hope you good luck

Try to use Surfer or Origin.

Try Matlab 5.3. It is a great package for plotting contours. As a matter of fact you can automate the whole process by generating the corresponding C++ code by using the Matlab Graphics Compiler and embedding the resulting code in your application.
