IFEM: Bottom Line
n If you can do matrix-vector product,
you can run iterative solvers like
conjugate gradient
n Matrix-vector product amounts to
the usual FEM calculation
(displacements to forces), plus the
usual FEM communication (update
shared nodes)
n You donít even need to store the matrix
n Users can easily solve iterative
problems with the FEM framework
and IFEM solvers!
