摘要

In this paper, we describe a method that will provide automated control over a dynamical simulation. Many simulations of physical objects have a dynamical scale, and cannot be adequately simulated with a fixed computational grid. The use of a proportional-integral-derivative (PID) controller provides an automated method to expand or contract the computational grid. We show the application of this method to the test example of a rarefaction wave expanding into vacuum. In addition, we present methods by which this procedure can be generalized to other physical situations.
