Hello:
Sorry for the inconvenience but I still cannot figure it out.The
algorithm my professor is working on is an implementation of a multiscale
finite element method.The key step of the multiscale finite element method is
to construct the basis function in each element. To construct the basis
function, we need to solve a local problem in each element. That is to say,
when we carry on the finite element method, the basis function in each element
is obtained by solving the local problem.
I have a triangulation object and it has been refined.Now I only
need to solve an equation on one of its cells and the solution will be regarded
as the basis function of an element in that cell.
Is there an easier way other than associating FE_Nothing elements to
other cells?I wonder if active cell_iterator could be somhow transformed into a
triangulation object such that I can solve the equation using the
techniques step-6 provide with only changes in the Coeffeicient
function.
Regards
Travis
