Time Dependent Heat Conduction Equation using Weak form

Please login with a confirmed email address before reporting spam

Hi
I am trying to solve the time dependent heat conduction equation using weak formulation. I have set up the problem by adding a square and two Drichlet BCs (the left u=1 and the right u=0, the top and bottom considered Zero Flux) and putting the PDE formulation of “ -ux*test(ux)-uy*test(uy)-test(u)*(u-prev(u,1))/timestep” then added discrete time solver as previous thread in this discussion forum however I got the error “Time 1 (sol2/t1)” (Attached File). I would appreciate if somebody could help me to find out how to solve the problem or share a file.

Hi all
I have solved the problem you need just to delete the time solver
