Re: [deal.II] Error when modify Step 29 into complex-valued problem

[Wolfgang Bangerth]

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.
