I want to learn a numerical method for PDEs other than finite difference method. After some research on internet i have found Rothe method and it looks interesting to me. Unfortunately, i couldn't find a good book/ notes for starting. Can you suggest me a book to study? What is prerequisites/corequisites for the Rothe method?

Thanks in advance...

    Rothe's method is semidiscretization in time before space (a transpose of the more common "method of lines"). That choice is orthogonal to the discretization scheme (finite difference/volume/element). I suggest reading about finite volume methods if you are interested in hyperbolic problems (wave propagation and similar) or finite elements if you are interested in elliptic or parabolic problems. – Jed Brown Dec 04 '14 at 19:53
  • @Jed Brown first of all thanks for answering my question. Actually i dont understand the relation between rothe method and finite element method. Can you explain that relation much more ? i will be grateful if you could. – math Dec 04 '14 at 20:12
  • FD is a space or time discretization. The distinction between Rothe vs Method of Lines is only whether you discretize in time-then-space or space-then-time. You said you want to go beyond FD, so read up on FV or FE. This is orthogonal to using Rothe vs Method of Lines. (I prefer MoL because I think it is much better at enabling software reuse.) – Jed Brown Dec 04 '14 at 20:55

  • Ok @Jed Brown thank you so much. can you suggest me a good introductory book for FEMs and a basic illustration of MoL – math Dec 04 '14 at 21:18

Here's a 30 minute introduction that explains the difference between the method of lines and the Rothe method: http://www.math.tamu.edu/~bangerth/videos.676.26.html
