HIF Analytic Work

Although numerical simulations are used for the detailed design and analysis of HIF experiments, analytic work provides a valuable complement.   This work is used mainly to develop advanced numerical methods and to assess the importance of physical effects that are not yet in computer models.

Anaysis has been extensively used to improve the numerical methods used in WARP and other simulation codes, resulting both in reduced running times and in enhanced realism.  Useful work has been done in the following areas:

The analytic work aimed at understanding physics that is missing from simulations includes several efforts: A final area where analysis proves valuable is the distillation of simulation results into scaling laws that can be used in the systems code IBEAM.
