Hello everyone:
I am using FEniCS based on C++, the question is stated as follows.
Assume \Omega_1=[0,0]\times [1,1] and \Omega_2=[1,0]\times [2,1], thus x=1 is an interface with facet id=1. Let V be some FunctionSpace on the mesh.
Now, if there are two Functions
Function f(V)
Function g(V)
Assume that f
and g
are two solutions computed by two bilinear forms. My question is how to copy the interface value of Function f
to Function g
? Something like the pseudocode below
g->vector()->(facetid=1) = f->vector()->(facetid=1)
I am not very familiar with FEniCS under C++, should I iterate the facet?
Thanks in advance,
Leon
