Physical units

By default, you can access and modify PyFluent solver settings according to its S.I. unit. However, PyFluent also allows you to work in arbitrary physical examples. Here’s an example:

>>> from ansys.units import Quantity
>>> hydraulic_diameter = solver.settings.setup.boundary_conditions.velocity_inlet["hot-inlet"].turbulence.hydraulic_diameter
>>> hydraulic_diameter.set_state(.02)
>>> hydraulic_diameter.get_state()
0.02
>>> hydraulic_diameter.state_with_units()
(0.02, 'm')
>>> hydraulic_diameter.set_state(Quantity(15, "mm"))
>>> hydraulic_diameter.state_with_units()
(0.015, 'm')
>>> diam = hydraulic_diameter.as_quantity()
>>> diam
Quantity (0.015, "m")
>>> diam = diam * 2
>>> diam
Quantity (0.03, "m")
>>> hydraulic_diameter.set_state(diam)
>>> hydraulic_diameter.as_quantity()
Quantity (0.03, "m")

You can find out more about using Quantity objects and other library features in the PyAnsys Units documentation.
