Dear Jie,
In your conclusion here the point 2 may be ambiguous,
> Apply nonzero_constraints at the first Newton iteration in every time
step.
Is that means:
use nonzero_constraints to distribute newton update or solution or both?
In my thought, in moving nonzero constraints case:
In
Thanks Wolfgang, I get the point!
Best

If I understand that correctly, the correct order for doing that would be:
-> Interpolate boundary condition without any component mask, giving me a
vector
-> Loop over all elements in the vector, and cross-check with the mask
(using extract_dofs()) if they should be interpolated in that way
->
I will take a look, thanks for the help! Would it be useful to have it in a
form which could be introduced in the library later (as drop-in replacement
for interpolate(), for example)?

I would like to use the interpolate()-function to interpolate the correct
function onto my mesh for comparison during some simple tests. This works
fine when using FE_Q-elements, but fails when using FE_Bernstein elements.
The error message I get is
