Dear all, I am trying to set-up a simple poisson system where I will change my RHS repeatedly, but the main system matrix will not change, so it will only need to be inverted once. I have been looking through the class definition for LinearImplicitSystem and its parent classes, but I don't see how to implement this. (I did run across a comment about multiple RHS in regard to the variable assemble_before_solve, but it's still not clear to me.)
Is there an example of this, or could you point me toward which member functions to use to accomplish this?
