Adding a Solution Setup to an HFSS Design

To add a new solution setup to a design:

1. Select a design in the project tree.

2. Click HFSS>Analysis Setup>Add Solution Setup.

• Alternatively, right click Analysis in the project tree, and then click Add Solution Setup on the shortcut menu.

• If you have an existing setup, you can Copy and Paste it, and then edit parameters.

• If you have already created a solution and you want to use an existing mesh, you can click Add Dependent Solve Setup.

The Solution Setup dialog box appears. It is divided among the following tabs:

General	Includes general solution settings.
Options	Includes settings for lambda refinement, adaptive analysis and solution options, the Order of Basis setting, and whether to enable the use of solver domains, and whether to Save Fields and/or radiated fields only.
Advanced	Includes settings for mesh linking, absorbing boundaries on ports, and waveport adapt options.
Expression Cache	Includes a list of expressions (including post processing variables) that you can use for convergence for adaptive analysis.
Derivatives	If your design contains variables, they are listed here. HFSS can calculate derivatives for your variables.
Defaults	Enables you to save the current settings as the defaults for future solution setups or revert the current settings to HFSS’s standard settings.

3. Click the General tab.

4. The Enabled checkbox on General tab permits to you to disable a setup so that it does not run when you select Analyze All.

5. For Driven solution types, do the following:

a. Enter the Solution Frequency and select the frequency units from the pull down list.

b. Optionally, select Solve Ports Only.

For Eigenmode solution types, do the following:

a. Enter the Minimum Frequency and the frequency units.

b. Enter the Number of Modes. The number must be greater than 0 and less than 20.

6. If you are performing an adaptive analysis, enter 2 or more passes in the Maximum Number of Passes box, and then specify the remaining adaptive analysis parameters for HFSS.

For Eigenmode solutions, if you are not performing an adaptive analysis, entering 0 will enable you to bypass the adaptive analysis process and just perform a frequency sweep. For driven problems HFSS always requires at least one adaptive pass. Entering 1 will also bypass adaptive analysis, generating a solution only at the solution frequency you specified.

7. Click OK.

8. Optionally, add a frequency sweep to the solution setup.
