Preconditioning distinct subsystem models in a subterranean region model

摘要

In some aspects, techniques and systems for operating a subterranean region model are described. A global system model represents a subterranean region. Subsystem models of the global system model are identified. Each of the subsystem models represents a distinct subsystem within the subterranean region and is associated with a respective governing equation. The subsystem models can be preconditioned based on the respective governing equations of the subsystem models. The global system model that includes the preconditioned subsystem models can be preconditioned. The preconditioned global system model can be operated.
