[Libmesh-users] Reusing the same stiffness matrix with different force vectors?

[James J R. <jjr...@po...>]

I noticed that the examples generally have the stiffness matrix and
force vector assembled in some function that becomes an argument to
the "attach_assemble_function" method. I have a possible application
in mind that involves using the same stiffness matrix with different
force vectors. Is there a way that I can do this without recalculating
the stiffness matrix each time?
