[Nek5000-users] Forcing term in weak form

[nek5000-users at lists.mcs.anl.gov]

Hi NEK's

I need to add a forcing term f to the linearized momentum equation which is
proportional to the divergence of the viscous stress
 div(grad(Ub)+grad(Ub)^T), where Ub is the base-flow.

Thus, if grad(Ub)+grad(Ub)^T=c I would like to use the weak form
formulation where *-c grad w* is used, instead of *div(c)*w* (w being the
test functions). Is it possible?
