The interpretation of these observations requires extensive theoretical work and computer modelling of the physical characteristics of NEOs.

Although computer models are important, the process of building the capacity of local experts is imperative in the exercise of mitigation assessments At the outset of a modelling exercise, there should be a clear distinction between generating information for the models and the actual work in computer modelling.

Century Dynamics continue to address the computer intensive nature of hydrocode modelling by assessing the correct balance between speed and accuracy.
