I am looking for a Windows program which can simulate
- plate tectonics,
- hydrodynamics, and
on a randomly-generated non-Earth earthlike world in as realistic a manner as possible.
It should be able to output a height-map with detail as fine as possible.
The ability to view the world (even in a low-detail manner) as the simulation is in progress is almost a necessity.
I am chiefly after believable results for game worlds, on non-earth worlds. I would be chiefly interested in producing detailed topological and hydrological maps. I'm perfectly willing to let a program that does this run for days or even weeks if necessary to get the results I want, so speed is not an issue.
Freeware would be a bonus, and open-source would be a further bonus, but neither is really necessary.
