Hi everyone,
I'm trying to solve a nonlinear ODE with Dirichlet conditions using
Newton's method. For this I give an initial guess for the solution ( y =
(1/2) x ) and then update each Newton step with an update that ought to be
zero at the boundaries (hence preserving the boundary conditions o

Dear all,
I'm facing the same problem and found this topic.
Is there any update on this issue or it is still the same as 7 years ago?
Thanks

Dear Bruno and Daniel,
Thanks for your replies.
I used linear_operator and then solve the problem like step-70.
I guess there is no "Direct solver" for this situation, the one like we had
for dealii BlockSparseMatrix.
Best regards,
Masoud

Thank you very much for pointing this reference out.
It is highly helpful and I think the community really appreciate you making
all these efforts to not only move science forward, but teach it in a
better fashion :)

Good morning,
I would like to ask if I import a Gmsh mesh, where the componeent y
coorresponds to the hight (and not z), will the everything inside Dealii
follows this coordinate systems, and keep the reference (0,0) from the mesh
I imported?
Thank you
