About the boundary condition for BDM element
Asked by
Feiteng
Hi all, I am reading the demo of FEniCS, and I'm confused with the demo/pde/
\int_f v \cdot n p ds, where p=1 or p=s for each edge(2D case).
And when the demo handle the boundary condition for the BDM_1, it just let
v[0] = g*n[0]
v[1] = g*n[1]
what does that mean? g*n[0] & g*n[1] is the evaluation of the degree-of-freedom? I'm confused.
Thank you.
