fenics-project / DOLFIN / issues / #225 - NonlinearDiscreteProblem should use system assembler if symmetric==True — Bitbucket

Issue #225 resolved

Jan Blechta created an issue 2014-01-31

Result of the long discussion is the revelation of this issue:

NonlinearVariationalSolver::NonlinearDiscreteProblem::J/F uses normal Assembler breaking a symmetry even if parameter NonlinearVariationalSolver.parameters['symmetric'] == true. In fact, this parameter is not used anywhere.

I wouldn't hurry with this for the same reason as https://bitbucket.org/fenics-project/dolfin/issue/167/cleanup-of-linear-solver-logic-needed#comment-14043406

Fixed in 2c293c5 by using symmetric assembler in all cases. Option 'symmetric' yet to be removed.

Option 'symmetric' yet to be removed.

Not necessarily. Cholesky/MINRES can be invoked rather than LU/GMRES.
