Describe the bug 🐞

I ran the parameters code example but reversed the order of the parameters Dn and Dp . Remaking the problem now causes the parameters to be switched in order, but this is hidden.

Expected behavior

Giving the parameters in the same order in discretize and in remake should re-set the same parameters.

Minimal Reproducible Example 👇

In the following code, the intention is that each parameter is incremented by a tiny amount, but the outcome is that they are switched (and incremented). The animation shows two quite different simulations, in spite of the intended increment being tiny.

using ModelingToolkit, MethodOfLines, OrdinaryDiffEq, DomainSets

@parameters t x
@parameters Dn, Dp
@variables u(..) v(..)
Dt = Differential(t)
Dx = Differential(x)
Dxx = Differential(x)^2

eqs  = [Dt(u(t, x)) ~ Dn * Dxx(u(t, x)) + u(t, x)*v(t,x),
        Dt(v(t, x)) ~ Dp * Dxx(v(t, x)) - u(t, x)*v(t,x)]
bcs = [u(0, x) ~ sin(pi*x/2),
       v(0, x) ~ sin(pi*x/2),
       u(t, 0) ~ 0.0, Dx(u(t, 1)) ~ 0.0,
       v(t, 0) ~ 0.0, Dx(v(t, 1)) ~ 0.0]

domains = [t  Interval(0.0, 1.0),
           x  Interval(0.0, 1.0)]

#@named pdesys = PDESystem(eqs, bcs, domains,[t, x], [u(t, x), v(t, x)], [Dn=>0.5, Dp=>2.0])
@named pdesys = PDESystem(eqs, bcs, domains,[t, x], [u(t, x), v(t, x)], [Dp=>2.0, Dn=>0.5])

discretization = MOLFiniteDifference([x=>0.1], t)

prob = discretize(pdesys,discretization) # This gives an ODEProblem since it's time-dependent
prob.problem_type.pdesys.ps
prob.p

newprob = remake(prob, p = [2.001, 0.5001]);
newprob.problem_type.pdesys.ps
newprob.p

sol = solve(prob, Tsit5());
newsol = solve(newprob, Tsit5());

sols = [sol, newsol]
using Plots
for (j, sol) in enumerate(sols)
    discrete_x = sol[x]
    discrete_t = sol[t]
    solu = sol[u(t, x)]
    solv = sol[v(t, x)]
    anim = @animate for i in 1:length(discrete_t)
        p1 = plot(discrete_x, solu[i, :], label="u, t=$(discrete_t[i])"; legend=false, xlabel="x",ylabel="u",ylim=[0,1])
        p2 = plot(discrete_x, solv[i, :], label="v, t=$(discrete_t[i])"; legend=false, xlabel="x", ylabel="v",ylim=[0, 1])
        plot(p1, p2)
    end
    gif(anim, "plot_$j.gif",fps=10)
end

Oh of course this is my minimal reproducible example of another project I'm working on, where I wanted to use the remake functionality rather than discretizing the problem again for each new set of parameters. The errors I got led me here.

I guess the tutorial would be easier to apply for other purposes if the parameters in the remake call were also given as pairs, with

newprob = remake(prob, p = [Dn => Dnval, Dp => Dpval])

This way the parameters will be kept in order.

Yes the tutorial should probably use the symbolic maps instead of assuming a data structure.
