Prerequisite¶
You need to have a working local installation of Ansys
1. Perform the necessary imports and create a QDesign in Metal first.¶

Create the design in Metal¶
Set up a design of a given dimension. Create a design by specifying the chip size and open Metal GUI. Dimensions will be respected in the design rendering. Note the chip design is centered at origin (0,0).

2. Render the qubit from Metal into the HangingResonators design in Ansys. ScatteringImpedanceSim will open the simulation software. Then will connect, activate the design, add a setup.¶
Review and update the setup. For driven modal you will need to define not only the simulation convergence parameters, but also the frequency sweep.
[10]:
em1 = ScatteringImpedanceSim(design, "hfss")
Customizable parameters and default values for HFSS (driven modal):
freq_ghz=5 (simulation frequency)
name="Setup" (setup name)
max_delta_s=0.1 (absolute value of maximum difference in scattering parameter S)
max_passes=10 (maximum number of passes)
min_passes=1 (minimum number of passes)
min_converged=1 (minimum number of converged passes)
pct_refinement=30 (percent refinement)
basis_order=1 (basis order)
vars (global variables to set in the renderer)
sweep_setup (all the parameters of the sweep)
name="Sweep" (name of sweep)
start_ghz=2.0 (starting frequency)
stop_ghz=8.0 (stopping frequency)
count=101 (total number of frequencies)
step_ghz=None (frequency step size)
type="Fast" (type of sweep)
save_fields=False (whether or not to save fields)

Add a frequency sweep to a driven modal setup. From QHFSSRenderer.add_sweep doc_strings. Please go to doc_strings to get the latest information.
Args: setup_name (str, optional): Name of driven modal simulation Sweep. Defaults to “Setup”. start_ghz (float, optional): Starting frequency of sweep in GHz. Defaults to 2.0. stop_ghz (float, optional): Ending frequency of sweep in GHz. Defaults to 8.0. count (int, optional): Total number of frequencies. Defaults to 101. step_ghz (float, optional): Difference between adjacent frequencies. Defaults to None. name (str, optional): Name of sweep. Defaults to “Sweep”. type (str, optional): Type of sweep. Defaults to “Fast”. save_fields (bool, optional): Whether or not to save fields. Defaults to False.
From pyEPR.HfssSetup.insert_sweep(), please go to this method to get the latest documentation.
You should provide either step_ghz or count when inserting an HFSS driven model freq sweep. Do not provide both or neither!
