Dear all, I would like to assign a different value for every cell for one of the coefficients of my pde. I have read all the values for my current discretization with numpy.genfromtxt into a variable. I also have the coefficient Function available. How can I assign now the values to the Function? Thank you! Henrik -- Dipl.-Math.
