However at these two last lines the excution crashes with the message
*You are trying an operation on a vector that is only allowed if the
vector has no ghost elements, but the vector you are operating on does
have ghost elements. Specifically, vectors with ghost elements are
read-only and cannot appear in operations that write into these vectors.*
why is this happening. I am not creating the system_rhs with ghost elements.
It's hard to tell without a complete example that shows the issue. Are
you sure the exception is triggered in the function you mention? Are you
sure that you don't modify system_rhs somewhere in between?
