[QUOTE]SuperL98;
I stumbled across an interesting Free Online flow simulator called “Flow Illustrator”
You can upload your own Bitmap images into it, so I figured I would try out a C4

Don’t know how accurate it is but fun anyway
See if I can get everything to post, got a little blurry eyed playing with this all day

The Bitmaps I made from a C4 technical drawing

And the Youtube videos, quality isn’t to good, unfortunately

The home page for Flow Illustrator is

http://chernyshenko.sesnet.soton.ac.uk/FlowIllustrator.aspx

You can modify & use my (24 bit) Bitmaps above
Click on bitmap and upload your image
2 :1 ratio images are best 640 by 320 , 512 by 256, etc
Re = Reynolds’s number = I used numbers in the 2,500,000 to 6,000,00 range
Dt = leave this alone, has to do with quality
Sec = video time – Anything over 40 sec takes forever.

Have fun!!![/QUOTE]
