I am a newer, and reading Step-21, but I can't find the implementation
of "\triangle t \sum_K \left(F(S^n) q^{n+1}, \sigma\right)_K"
in the function "assemble_rhs_S". This, of course, doesn't affect the
result, because in the example, there is no source, q=0.
Yes. We simply didn't implement the term in the program since it would
always be zero.
However, for a more general case, is it right? I want to know what's
wrong with it or with me.
You're right that in a more general case this term would need to appear
in the program.
