An Overview of the Foundations of Ansys HFSS and Ansys Maxwell Solver Technologies

The second installment of the Electromagnetics Foundation Webinar Series is here. In this webinar, you'll gain a deeper understanding of the mathematical underpinnings of both HFSS and Maxwell, including solver approaches and differences between them and a review of advanced capabilities.

The webinar has past, but you can still get the recording by filling out the form.

About this Webinar

Ansys HFSS and Ansys Maxwell are the premier electromagnetic simulation tools used by engineers for over 40 years to design all kinds of electronic products such as antennas, PCBs, connectors, electric motors, transformers, etc.

This webinar covers an overview of the critical foundational technologies for HFSS and Maxwell, plus the recent advanced features. The various numerical methods (finite elements, integral equations, etc.) included in both products will be discussed and positioned with solver options such as direct and iterative algebraic solvers.

HPC options can solve significant problems and dramatically reduce simulation time. We'll also discuss the automatic reduction of the simulation design space for Maxwell to minimize simulation time significantly. We'll highlight Maxwell's advanced physics modeling techniques, such as vector hysteresis, the irreversible effect of temperature on demagnetization, magnetostriction modeling and Litz wire modeling. In addition, an integrated workflow example for multiphysics coupling will be shown, from thermal management to noise, vibration, and harshness.

What you will learn

  • Learn the foundational technologies of HFSS and Maxwell
  • Get an overview of the numerical methods used by HFSS and Maxwell
  • See the key solver options such as direct and iterative algebraic solvers
  • Understand the types of applications that two different Maxwell field formulations can solve
