Oh yeah? Let's take a combustion engine as an example. I have a the solid parts
modeled with MARC, and the fluid parts modeled with PHOENICS. According to Don,
it would be a "tractable" matter now to roast the beef. 

Or else, let's start from the basics: take some F.E. ingredients for the solid
parts, take some F.V ingredients for the fluid parts. Then ... take a BIG MAMA,
and "the problem easily reduces to a tractable form".

One world or no world. Once F.V. and F.E. have been unified into ONE universal
numerical method, the true practical problems will remain hard enough to solve.
