I am following the tutorial on transient Stokes solver. In the last code snippet, I find the following line:
w1=sol; u=w1; v= w2; p=wp;
which saves the solution from
w1 corresponding to a
P2,P2,P1 mixed space to individual variables
p corresponding to spaces in
I want to do the opposite of it where I have variables in individual spaces and convert them to a combined mixed element space. I want to achieve this so that it becomes easier to write the data using
ofstream and access it in another code.
