I am trying to solve an eigenproblem. I would like to apply
boundary conditions by removing the rows and columns associated with
these dofs (as opposed to retaining/zeroing them and setting the
diagonal elements to unit values).
Is there a way for me to tell the matrix data structure which dofs
to ignore during the matrix operations? Or should I create a separate
matrix by extracting the unconstrained dofs from the global matrix?
I would appreciate any inputs.
