Angles

PyAnsys Units treats angles as non-dimensional unit quantity by default but it supports configuration of angle quantities as dimension. Angle quantity units such as degree, radian and solid angle can be treated as dimension.

You can set the environment variable PYANSYS_UNITS_ANGLE_AS_DIMENSION to treat angle quantity units as dimension.

Angle as non-dimension

import ansys.units as pyunits

degree = pyunits.Quantity(1.0, "degree")

degree.is_dimensionless  # True
degree + 1  # Quantity (58.29577951308232, "degree")

Angle as dimension

import os

os.environ["PYANSYS_UNITS_ANGLE_AS_DIMENSION"] = "1"
import ansys.units as pyunits

degree = pyunits.Quantity(1.0, "degree")

degree.is_dimensionless  # False
degree + 1  # Not allowed
