Abstract

This paper summarizes the Orthomin¹ and GMRES² linear solvers. It presents a mapping from the Orthomin residual basis over to the GMRES basis that is used to switch solvers dynamically during the linear solve step in a reservoir simulator. This mapping enables a combined algorithm to adapt easily to problem complexity .
