@Akanksha, Wow! I stepped out for a day and so much activity already on puzzle #2874. I learned a little bit about CFD when I worked for Center for Development of Advanced Computing in Pune and now I am hearing about it everyday from my son as he is researching on the same subject. @Rihana, how much ever I try to be away, this thread gets me back like a magnet. What to do? Viswa
#2874 Akanshas puzzle, I was able to link 5 images to a person without looking at high flying clues. Shall wait for the answer.
