Computer models of planetary dynamos cannot operate in the appropriate parameter regime for planets. In order to use these models to learn about planetary dynamos, we use scaling laws to find trends for particular field properties that we can then scale to the planetary regime. We have worked to understand the influence of boundary conditions,  as well as material and physical properties on dynamo simulations in order to better model planetary magnetic field generation.
