Re: [Libmesh-users] How to extract ALL dof indices for a given variable

[Derek G. <fri...@gm...>]

I guess... instead of asking how to do that I should say what I really want
to do: zero a variable.  So if I have 3 variables in a system (u,v,w) I
just want to zero 'v' and not the other two.  I was thinking of doing this
by snagging all of the dof_indices for v and then calling set() and passing
those in along with 0.  Is there a better way?
