Dear Deal.II community, I'm getting trouble in developing new code based on step-25. In step-25, the equation to be solved is u_tt−∆u=−sin(u) and the tutorial shows me how to solve such a nonlinear problem.
Specifically, the tutorial tells me how to calculate (sin(u),φ_j)_Ω in detail. So I 'm wondering how to solve such a problem which is like u_tt−∆u=∇∙V, where V is a vector and its components(x direction and y direction in 2D) are dependent on u. So could you please give me some advice about doing this or any reference in existing dealii examples. Thank you very much. -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
