A thermal model of an espresso cooling in a porcelain mug, built with Dyad. It captures convection, conduction, and radiation across interacting subsystems — the coffee, the mug, a hand, the rising steam, and an optional metal spoon.

The model ​

EspressoCupSystemModular connects the coffee-mug, steam, and hand subsystems to a fixed-temperature ambient environment:

Running it ​

Simulate the espresso cooling over 6000 s and plot the espresso temperature:

julia
using CoffeeMugDemo, ModelingToolkit, DyadInterface, Plots

@named model = EspressoCupSystemModular()
res = TransientAnalysis(; model, alg = ODEAlg.Auto(),
                        abstol = 10e-3, reltol = 1e-3, start = 0.0, stop = 6000)
plot(res, idxs = [model.coffeeMug.espressoTemp_degC])
