yy.wayne:The error message says that the function object you pass to interpolate_b_v has two vector components, but the finite element space has only one vector component. That's because in step-29, you needed two vector components for the boundary values (for the real and imaginary parts) whereas you are now defining a scalar finite element space with only one vector component. You need to adjust the object that provides boundary values appropriately.

*** Caution: EXTERNAL Sender *** Hi my friends,I'm trying to modify step29 into a complex-valued problem as my project for deal.II, where you do not seperate real part and imaginary part like the original tutorial. However error shows up in interpolate_boundary_condition funtion. Here is the error output but I cannot locate where dimensions are not fitting.Snipaste_2022-09-25_10-58-31.png and the c++ code file: --The deal.II project is located at http://www.dealii.org/ <https://nam10.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.dealii.org%2F&data=05%7C01%7CWolfgang.Bangerth%40colostate.edu%7Cfbdc82ddb44644ad4f1c08da9ea1fb5d%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637996715835974004%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=7S6mTjGa9lCh757GZb%2B2M2eP3AcndEjMEDxZTBdVmRw%3D&reserved=0> For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en <https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgroups.google.com%2Fd%2Fforum%2Fdealii%3Fhl%3Den&data=05%7C01%7CWolfgang.Bangerth%40colostate.edu%7Cfbdc82ddb44644ad4f1c08da9ea1fb5d%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637996715835974004%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=BqhNOhfRaia%2By5nJYBQXDNc5%2FzbDf3hl8TZHGRMsLD0%3D&reserved=0>---You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
