Re: Fluid Flow Applications
I haven't seen something similar, however for CFD there are to codes that might interest you
OpenFOAM, a complete (well nearly complete) CFD suite. Although it has a mesh generator, this is very primitive, so you have to use a third party mesh tool if you want more complex geometries

ELMER multiphysics
both run on LINUX Ubuntu pretty well
hope this helps...
Re: Fluid Flow Applications
No, this isn't really what I'm after, although OpenFOAM is an amazing package it is too complex for what I have in mind. I was wrong to suggest FEM tools, I meant to say electrical circuit simulators. I'm having a look at qucs for starters.
