Defining fluid domain in 3DX

Its good to change for a while so that interest continues. I have been writing incessantly since years and my total blog count will soon approach one hundred. Before hitting the magic number I thought of rattling for a while by sharing vignettes. That would give me an opportunity to show something live and hands on. So the theme for next two to three postings is “how” instead of “why” and I am picking computational fluid dynamics as the starting topic.
