I think I mentioned this before: You can't. The entries of the stiffness

Hello Wolfgang,
thanks for your reply.
I wonder whether the stiffness matrix could be converted to a matrix with
rows = cell_numbers and columns = cell_numbers.
I tried to write the gradient with rows = degree_of_freedom into with rows
= cell_numbers.

How do you define "stiffness matrix in global cells" mathematically?

Hello team,
may I know how the stiffness matrix in global degrees of freedom could be
converted into stiffness matrix in global cells?
I would like to use cook_memebrane.cc to get a stiffness matrix in a way of
global cells.
Currently,I only got the stiffness matrix
