Variable

This module provides all functionalities for creating and editing design and project variables in the 3D tools.

from ansys.aedt.core import Hfss

app = Hfss(
    specified_version="2025.2",
    non_graphical=False,
    new_desktop_session=True,
    close_on_exit=True,
    student_version=False,
)

# This call returns the VariableManager class
variable_manager = self.aedtapp._variable_manager

# Set and get a variable
app["w"] = "10mm"
a = app["w"]
...

VariableManager	Manages design properties and project variables.
Variable	Stores design properties and project variables and provides operations to perform on them.
DataSet	Manages datasets.
CSVDataset	Reads in a CSV file and extracts data, which can be augmented with constant values.

Quantity and numbers

Quantities with units can be managed using the class Quantity.

from ansys.aedt.core.generic.numbers_utils import Quantity

a = Quantity(1, "GHz")
b = a + 1
c = a + "1MHz"
d = a + b
a.unit = "Hz"
e = a.to("MHz")
str(a)
float(a)
hfss = ansys.aedt.core.Hfss()
setup = hfss.create_setup()
setup.props["Freq"] = a

Quantity

Stores a number with its unit.
