Hey there, I’m new to Julia and I wanted to transport my existing FEM Code written with FEniCS in C++ to JuAFEM code. First of all thanks to the developers of the package! My problem is a SUPG stabilized advection diffusion system \int c_{n+1} v \ dΩ + \int c_{n+1} \cdot (\delta_T \mathbf{u} \cd…

Sorry, my patch above is not quite right, you of course need to use the copied A for the solution too: --- a/main.jl +++ b/main.jl @@ -135,8 +135,9 @@ for t in 1:Δt:T update!(ch, t) # load current dbc values from input_exp global b = Δt*f + M * c_n # get the discrete rhs - apply!(A, …

This video has a bit more detailed description of the algorithm:

FWIW, I would highly recommend the whole lecture series by Wolfgang: https://www.math.colostate.edu/~bangerth/videos.html
