Dear Wolfgang,
to compute values of the electric field at the receivers I follow the
strategy of ASPECT code as you suggested
To do this I sum the current_point_values across processors and divide by
the number of processors that contain point p as following

Giovanni,
It looks like you are doing a lot of things similar to what we do in this
project https://github.com/ORNL-CEES/DataTransferKit In particular, one of
our subroutine allows the user to ask for the value of the field at
arbitrary points. We need our code to use GPUs, so we based our algo
- Does Cellid contain some information about the owners? Could it be
useful for a process to pass Cellid to another process CellId? I mean:
modifying the
find_point_location could the Cellid give information about where to
start looking for that point?
CellIds are globally unique, so you can
Hi, all
I was practicing using Petsc library through deal.ii wrappers,
While, step 17 gives me clear explanation, I am having trouble in
distributing hanging node constraints on Petsc system matrix,
I was modifying step-9 hyperbolic equation solvers with PETSc matrix, but
when I compile my
Hello Prof. Bangerth,
Thank you very much for the explanation. It really helps to understand FEM
and the dealii library.
I am glad to find this group to discuss things on FEM and dealii.
Best,
Yiyang

Suppose we need to solve some PDE about some function u(r). Following the weak
form of an equation, we obtain and solve a linear system (A*x=b). What we
really solve are the coefficients U_j (this corresponds to the vector x in the
linear system). Thus I am assuming that the solution vector (n
