Simulation and Engineering: State of the Art?

In conversations with work colleagues, we often discuss and debate the question, “What constitutes a state-of-the-art simulation tool?” Having worked in the simulation world for 25 years, I say that the time for a “state-of-the-art simulation tool” has passed. I now answer anyone who asks me, “It is not a tool that represents the state of the art but, rather, a methodology.”

There are many tools that simulate various things, and many of them are quite good. For example, I am firmly convinced that ANSYS HFSS represents the gold standard of 3-D computational electromagnetic simulation tools. However, this is simply one tool in a bag of tools used by engineers; individual tools by themselves do not represent the state of  the art in simulation.
