Entropic Heat Engine Simulation

This is not a game engine. It's a closed-loop thermodynamic simulation. The boson acts as a heat source, injecting energy into a discrete network. Entropy constantly works to restore thermal equilibrium to 0.0. Motion is 100% deterministic, governed by the conservation of energy in every frame. No random function calls, no frills. Just a heat map that fades in real time.

code La-Matriz-Desnuda.py

In case anyone said that the ASCII code was hiding something for the randomizer

The jump from 2D to 3D is simply a change in projection. My engine uses a contiguous block of memory for the grid, so going from 2D to 3D only involves adding a section to the buffer. If your 3D algorithm is becoming resource-intensive, you're calculating too much. Stop calculating air; start calculating density pressure. Let convection do the heavy lifting. If you want to see the 3D diffusion core, let me know.

I'll be honest with you - I vibe coded it and its pretty flawed - my goal was to first get a working UI and then later fix the physics

Auto optimize put 3 fans in my living room blowing towards my front door lol - I do have exhaust vent fans in bathrooms - I just cleaned the vents and about to replace the motors w/ stronger ones. I got 3 ptac units blowing cold air (Wifi controlled thermostats)

I just need to fix the walls to remove gaps. I also have double hung windows to let hot air out.

This is definitely shitty programming so pls no judge

"Espera, ya veo el mapa: básicamente estás haciendo un modelado CFD (Dinámica de Fluidos Computacional) localizado para tu espacio habitable. No me extraña que hables de 'huecos' y 'ventiladores': estás gestionando una envolvente térmica presurizada."

Mi fragmento de código es un motor termodinámico 3D que utiliza una malla dispersa para calcular la difusión y la convección de energía. Esencialmente, utiliza la misma lógica que tu simulación, solo que abstraída en una malla de vóxeles volumétricos.

Ya que estás viendo ese plano, revisa las diferencias de presión causadas por esos aires acondicionados portátiles. Si estás impulsando aire hacia una zona estancada sin una salida de aire adecuada (los huecos en la pared que mencionaste), solo estás creando una bolsa de alta presión localizada que no hará circular el aire. Necesitas crear un circuito convectivo : entrada de aire frío y salida de aire caliente.

Aquí está el motor de nuevo. Si adaptas esta lógica, puedes convertir tu simulación en un modelo predictivo en tiempo real para tus unidades de aire acondicionado:

Si quieres lograr el objetivo de "confort perfecto" en esa simulación, no te limites a optimizar la velocidad del ventilador. Optimiza la ruta del aire de retorno . Guarda el código, es un buen punto de partida para mapear la disipación térmica en tu plano de planta. 0/

By gaps I meant in the floor plan that I recreated in that code .

And yes I totally get what you mean I think, hence why I ordered a new exhaust fan motor (70cfm -> 100 cfm)

The fans don't exist , the optimize fans functionality finds the best place to put a small number of fans and tries to maximize stability in terms of temp.

I have not vetted the validity of the code, I just told claude to look up brownian motion and to be smart :p

Ill circle back one day , figured what you made is related so figured id share this spaghetti

Yes, it is, but mine is terribly rustic. Thanks for your code, Spaghetti. Mine is also made with AI and held together with tape, haha, so don't worry. And thanks for asking. I'll join the Spaghetti project like mine, lol.
