Dear all, It is not very clear to me what is the order followed when using multi-components. As an example to put my question more clear I cann point to step-29 where there are 2 components used.
My common sense would be that the system_matrix global operator would have first real and then the imaginar components. However, printing the matrix and looking at it, I can see the values are somehow intercalated (rows and columns). *Could someone please clarify this?* I would also like to ask how can I get the mass matrix of one of the components. Using the following for each cell and locating for the global matrix I get the two components (again not sure how the order is...) *Mass_matrix(i,j)+=((fe_values.shape_value(i, q_point) * fe_values.shape_value(j, q_point)) * fe_values.JxW(q_point));* On the other hand, using the following, does not allow me to use the local_dof_indices function, as using only one component, the dof is half: *Mass_matrix(i,j)+=((fe_values.shape_value_component(i, q_point,0) * fe_values.shape_value(j, q_point,0)) * fe_values.JxW(q_point));* *What is the best way to get this?* Thank you very much for your time. -- 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.
