Feature: Remove Implicit RHS Evaluation in Autonomous Problems With the Trivial Predictor #495

Closed gardner48 closed 6 months ago

gardner48 commented 6 months ago

Add the function ARKodeSetAutonomous to indicate that the implicit right-hand side function does not explicitly depend on time. When using the trivial predictor, an autonomous problem may reuse implicit function evaluations across stage solves reducing the total number of function evaluations.
