Hi I am trying to solve the underlying system: eq = [ρ*Cₚ*Dt(T(x,y,t)) ~ kₓ*Dxx(T(x,y,t)) + ky*Dyy(T(x,y,t)) + H*W*Re , Re ~ A*exp(-E/(R*T(x,y,t)))*c(x,y,t)] The Domain is : domains = [x ∈ Interval(x_min, 0.013), y ∈ Interval(0,0.065), t ∈ Interval(0, 60*100)] the system w…

If it is radial distance, I think the correct diffusion operator should be kₓ*(Dx(x*Dx(T(x,y,t))))/x and you get [image] But if you used exactly the same equation kₓ*Dxx(T(x,y,t)) in your reference solution it still does not explain the delay you observed. If on the other hand your reference so…

How do you know it’s not a property of the discretization?
