Tips to create effective simulation models

This is from a panel discussion at the Regional Simulation Conference last month, where I underlined the significance of having a deeper understanding of physics to identify the best simulation strategies.

o?? It has been especially helpful to define the hypothesis well in advance and to make clear what outcomes we hope to obtain from simulations.

o?? Just because we have advanced computing capabilities does not mean that we should consider every parameter we believe would have an impact on the result. Usually, we only need to take a few crucial factors into account.

o?? When both physical models are equally correct, multidisciplinary simulations and optimization make sense; otherwise, we might end up at an erroneous optimal state.

o?? We don't need to aim for perfection; if we understand the physics well, we can still create less accurate models and apply them successfully.

o?? Making decisions is more important than perfecting the simulation technique; as simulation engineers, we get carried away with increasing accuracy without considering whether it's truly necessary or whether it would affect the results.
