Hussan -- can you be more specific about your question? step-57 has a rather
lengthy discussion of how exactly the system is solved:

Zeb,
you'll have to be more specific. How about you show us the equations you want
to solve, what others in the literature are doing, how you think that the
solver/preconditioner step-57 might relate to your system, etc.

This is a site where we are happy to help, but we can't read your mind and you
can't expect us to take a one-line question, do several hours of research to
think about how one might solve your problem, and then report back. You can
ask questions, but you need to do your job in doing the work.

Best
Wolfgang

Dear Zeb,

To expand on what Wolfgang said in his previous email, we have a page that provides some hints on how to formulate a question that you can then engage the community with. Please give it a read, and have another go at asking your question!

Best,

Jean-Paul
