Model library
The library ReachabilityModels.jl contains a collection of pre-made models that can be found in books, articles or other publicly available software related to reachability analysis. As it is explained in the documentation of that library, once installed use it as:
using ReachabilityModels, Plots
prob = fetch_model("building") # initial-value problem
sol = solve(prob, T=5.0); # solve it using default options
plot(sol, vars=(0, 25)) # plot the solution
