RF deigns are getting more and more complex. Previously, engineers would cascade S-parameters together. Obviously, this approach ignores so many interactions and cross couplings rendering it inaccurate. Now, engineers need to do full wave simulations for the whole RF front-end and very often the surrounding environment. While such an approach is accurate, it is computationally very expensive. ANSYS HFSS, offers many HPC capabilities and a myriad of solvers. However, it is the technical know-how that is key for fast, accurate and reliable simulation. In this blog, we at cadfem we will show the most efficient ways to speed up your HFSS simulations.
