Addressing Electrically Large Antenna System Design with ANSYS HFSS Hybrid Simulation

Presented by:Dr. Larry Williams, Director Product Management, ANSYS

With recent improvements in the efficiency of integral equation solutions, it is now possible to combine the integral equation procedure with the finite element method (FEM) in a hybrid finite element boundary integral (FEBI) approach. In electromagnetics, the FEM is a general purpose technique that solves for volumetric electric fields; for antennas or scattering problems, the air region surrounding the model must be included. The integral equation (IE) approach, which solves directly for currents on object surfaces, is often more efficient for large open problems because it does not require the surrounding air volume.

Attend this webinar to discover how, by combining the two approaches in an FEBI technique, you can use ANSYS HFSS to accurately and efficiently simulate very complex, large, open electromagnetic problems. Learn the details of the IE solver technology currently available in ANSYS HFSS and how you can put it to use in solving your toughest antenna design challenges.
