I'm no expert, but I have tried using a bigcgstab solver in the past.

It is an iterative solution which  can provide more efficient  
solutions for large systems of equations.

My attraction was based upon my understanding that it would be quite  
attractive for time dependent or frequency dependent solutions where  
prior solutions may be used to determine the initial solution for  
subsequent solutions.
