I'm trying to solve equations for concentration which change over space (x) and time (t)
I never work with PDE, usually only ODE. So of course it does not give results like i want.
Can you please help?
I don't experience any download errors - the file is perfectly OK concerning file integrity.
Maybe your systems don't like the comma in the file name!?
Here is the file - renamed and also zipped
The way you set up the problem, it seems that you want a numerical solution. If so, all the values of the known terms, the initial and the boundary conditions are missing.
