What program can you use to simulate physics?

Question

Physics

Good morning comrades.
I had an idea for a new engine, I would like to draw a drawing and run it in an emulator. Are there any similar programs, or do I need to master something serious like AutoCAD?

Answer 1

Depending on what area of ​​physics. Usually, the simulation of "physics" means the simulation of mechanics, there are practically no problems with this today - a lot of great softwaresolves this problem. Another thing is that to simulate all aspects of the operation of a piston or turbojet engine (which one do you have by the way?), Mechanics alone is clearly not enough. To simulate and calculate the movement of fuel through fuel chains, simulation of hydrodynamics, gas dynamics and thermodynamics is needed. And for such a set of tasks, there is practically no ready-made software. Theoretically, all these applied areas can be generalized and simulated through molecular kinetics (all laws of dynamics of any media are derived through molecular kinetics), but here a completely different order of computing power begins: one second in a molecular kinetic simulator (for example, the process of fuel combustion in a jet engine) can take hours on supercomputers or years on home desktops.
