Setting up an HFSS Design

To set up an HFSS design, follow this general procedure. After you insert a design, you do not need to do the optional steps nor perform the intermediate steps sequentially, but you must complete them before you generate a solution.

Inserting an HFSS Design Selecting the Solution Type Set the Model Units Drawing a Model Assigning Materials Assigning Variables 3D Component Libraries Assigning Boundaries Assigning Hybrid Regions Assiging Excitations Adding a Solution Setup Adding a Frequency Sweep Optimetrics Running Simulations Post Processing and Generating Reports

Insert an HFSS design into a project.

  1. Select the solution type.
  2. Set the model's units of measurement.
  3. Draw the model geometry and assign material characteristics to objects.
  4. Optionally, Working with Variables.
  5. Assign boundaries, which specify the field behavior at the edges of the problem region and object interfaces.
  6. Optionally, assign Hybrid Regions, which invoke other solvers for areas you assign as FEBI, HFSS-IE, Physical Optics, SBR+ or Dielectric Cavities.
  7. For Driven solution-type designs, assign excitations - sources of electromagnetic fields and charges, currents, or voltages on objects or surfaces.

For Composite Excitation Solutions, you provide a complete set of excitations via the Edit Sources dialog before solving.

  1. Optionally, add 3D Components.
  2. Specify how HFSS will compute the solution.
  3. Optionally, Set up any Optimetrics you want to run.
  4. Run the simulation.
  5. View solution results, post-process results, view reports, and create field overlays.
Note:

After a period of idleness of 10 minutes, HFSS gives up its license. A renewal of activity automatically requests a license. Such idle notifications do not occur during solves.
