Is it possible to do simulations of electricity and magnetism in Blender, whether with addons or not?
I've seen that I can give particles charges, and simulate magnetic fields, but can I simulate induced magnetic fields and induced voltage?
Was going through some of my dad's old sketches and thought that his railgun-like thing looked interesting to try and simulate.
Use Unity or Unreal Op, they have programmable fully customisable physics engines that is accessible if you can code. They're a much better fit for what you wanna make than what you have available in a 3D content creation suite.
It isn't built for what you're wanting to do. Those "simulations" are for artistic uses, not real-world accuracy.
Now, if you're a python scripter, you might be able to shoehorn something like that in, but honestly you're probably better off going to >>>/sci/ and asking them about it. There is much better software available for this purpose.
Um, yeah? Lots of people have railguns. They aren't that hard to build if you're a tinkerer. Just search for "railgun" on youtube. Making them practical weapons is the hard part.
Something tells me this guy's dad's sketches are closer to the "look what I built in my garage" variety over the "Look what we mounted on a Cruiser for $50 billion."
