openmc VS monteCarlo

It was actually invented for this.

Open source radiation transport Monte Carlo code here if you'd like to play around:

Even given their nuclear weapons origin, we lowly civil nuclear power engineers still use Monte Carlo methods all day every day. We all make our employers buy big supercomputers or get us access to the national lab leadership class HPC to just pound the hell out of our reactor design problems with random particle transport chains. Sure there are (dramatically) faster deterministic methods that are generally good enough, but Monte Carlo allows you to use exact geometry and not bother too much with the pesky art of computing average nuclear interaction probabilities.

Heck, my buddy at MIT made an open-source Monte Carlo code called OpenMC that's now run by Argonne National Lab [1]. Now everyone can do truly legit reactor design with Monte Carlo!

I wrote a Monte Carlo area calculator once. Just draw an arbitrary shape and hit solve. You can increase the number of samples used.

Yeah. I wrote, a long time ago, a small experiment where you can calculate the area of a crazy drawn shape and approximate it's area using monte carlo simulation.
