Introduction to Ansys HFSStwo-day course
This course provides an introduction to the HFSS environment of the Ansys Electronics Desktop (AEDT) Suite. The general problem addressed is that of the high frequency electromagnetic field. The course focuses on the use of the HFSS user interface. This tool is included in the Ansys HFSS Premium and ANSYS Electronics Enterprise licenses. Within this interface, one can create CAD geometry, import CAD geometry, assign material properties, apply excitations, perform solutions, and review analysis results.
The course presents solutions to general electromagnetic problems encountered by most antenna/RF designers. Approaches for calculating characteristic impedance, S-parameters, electric/magnetic fields, and near/far fields are covered. Most workshops begin with projects where CAD geometry has already been prepared or is drawn in the tool as part of the exercise. DRD encourages students to bring ACIS files with them to the training (preferably from their workplace) if they desire to test their own geometry.
Module 1: Overview of HFSS
This workshop introduces the HFSS application via a previously set up simulation of a microwave band pass filter.
Module 2: Boundaries and Simulation Space
This workshop starts with a project that does not yet have the open region boundary assigned. The user will create both the region air box and the radiation boundary assignment.
Workshop 2.2 — Coax Bend Finite Conductivity Boundary
This workshop demonstrates how to change the default PEC boundary on an HFSS coaxial bend model to a finite conductivity boundary.
Module 3: HFSS FEM Solution Setup
Workshop 3.2 — Band Pass Filter Broadband Mesh
This workshop demonstrates the broadband mesh capabilities of HFSS on a microwave filter simulation.
Module 4: Simulation Post Processing
Module 5: Geometry Construction
Workshop 5.1 — Microstrip Bend Geometry Construction
This workshop demonstrates creating parameterized HFSS geometry from scratch. The geometry created is a microstrip transmission line with a right-angle bend.
Workshop 5.3 — Assigning a Finite Conductivity Boundary to Band Pass Filter
This workshop changes the default PEC boundary on a band pass filter example to a finite conductivity with aluminum properties.
Module 6: HFSS Lumped and Wave Port Basics
This workshop demonstrates exciting a wave guide with wave ports and post processing the results.
Module 7: Optimetrics and High-Performance Computing (HPC)
Workshop 7.1 — Microstrip Bend Parameter Sweep
This workshop demonstrates a parameter sweep and tuning exercise on a microstrip bend.
Workshop 8.1 — 30mm Coax Construction and Simulation
This workshop is an unscripted exercise to practice HFSS concepts with no detailed instructions. Only a general outline of the problem is provided.
