I'm still going through your entire response, but I realized that this statement made it possible for me to make a concrete design suggestion for the model:

The model must be able to describe simulations for which there is no target object.

Some physics models have application on a range of scales, like turbulence and Plummer spheres. For turbulence, the target object is really "compressible fluid", which doesn't carrying the same meaning as "cloud". Especially since the simulation results could be applied to molecular clouds or the Jovian atmosphere.

I think the target object is useful for most simulations, since we often are numerically modeling a particular type of object (cloud), or even a particular object (Perseus). But, not all simulations, especially the ones that are more of numerical experiment than a numerical model.
