I am looking for a way of getting some intuition for some Convection Diffusion Equation. I would like to play around with it, simulate it, change its IC/BCs, having some interactive graphs and stuff.

Do you know of any free software that does the job? Thank you!

OpenFOAM might also be a tool. But I am not sure, if this might be too begin with. – k1next Jan 21 '13 at 13:22
@macydanim: Could you form that into an answer? Thank you! – vonjd Jan 21 '13 at 13:30
Done, but I just noticed that you asked this question two years ago, sorry. – k1next Jan 21 '13 at 13:46
@macydanim - But I am still interested :-) Thank you – vonjd Jan 21 '13 at 13:52

Dynare on top of Octave should do the Trick.

OpenFOAM might also be a tool. But I am not sure, if this might be too difficult to begin with.

You can find it on their homepage. A quick google search offered this tutorial, see slide 17ff, where the convection-diffusion equation is solved. But I personally would start with the OpenFOAM tutorial.
