Hi,

first of all: 
"The "analysis/simulation engine" is 
 completely supplied by the user, written 
 in Mathematica, and contains all the physics."

*and*
"I'm happy to write the "analysis/simulation engine" 
 in C, C++, or any appropriate language."

can you make a decision ? *what* you whant ?

It is quite stupid to use a computer algebra for numerical intensive
tasks. I would *never* consider a number crunshing application
in Mathematica. Typical I try some ideas "how to solve" the problem
with Mathematica and put the result in a C/C++ program. That's
the reason why I have more than 15 MathLink programs.

Since the output of simulation data is very inconsitent,
numbers, arrays, images, text messages, 3d models, vector fields,
 ... you have to invent a general data base format that cover
*all* kind of possible data. More over you have to invent a
user interface that handle *all* kind of possible data by
buttons, input boxes, sliders ... 

The resulting system will be so complex (and slow) that 
you will not find a user ... 

Regards
  Jens
