Define materials

PyFluent allows you to use settings to interact with materials settings.

Copy material from database

>>> import ansys.fluent.core as pyfluent
>>> from ansys.fluent.core import examples
>>> file_name = examples.download_file("mixing_elbow.cas.h5", "pyfluent/mixing_elbow")
>>> solver = pyfluent.launch_fluent()
>>> solver.settings.file.read_case(file_name=file_name)
>>> materials = pyfluent.Materials(settings_source=solver)
>>> fluids = materials.fluid
>>> fluids.make_a_copy(from_="air",to="air-2")
>>> air_copy = fluids["air-2"]
>>> from pprint import pprint
>>> pprint(air_copy.get_state(), width=1)
{'chemical_formula': '',
 'density': {'option': 'constant', 'value': 1.225},
 'name': 'air-2',
 'specific_heat': {'option': 'constant', 'value': 1006.43},
 'thermal_conductivity': {'option': 'constant', 'value': 0.0242},
 'viscosity': {'option': 'constant', 'value': 1.7894e-05}}
>>> pprint(air_copy.viscosity.option.allowed_values(), width=1)
['constant',
 'piecewise-linear',
 'piecewise-polynomial',
 'polynomial',
 'expression',
 'power-law',
 'sutherland',
 'kinetic-theory']
>>> air_copy.viscosity.value.set_state(1.81e-05)
>>> elbow_fluid = pyfluent.FluidCellZone(settings_source=solver, name="elbow-fluid")
>>> elbow_fluid.material.set_state("air-2")

Create new material

>>> mysolid = materials.solid.create("mysolid")
>>> mysolid.chemical_formula.set_state("SiO2")
>>> mysolid.density.value.set_state(2650)
>>> mysolid.specific_heat.value.set_state(1887)
>>> mysolid.thermal_conductivity.value.set_state(7.6)

>>> myfluid = materials.fluid.create("myfluid")
>>> myfluid.chemical_formula.set_state("H2O")
>>> myfluid.density.value.set_state(1000)
>>> myfluid.specific_heat.value.set_state(4186)
>>> myfluid.thermal_conductivity.value.set_state(0.6)
>>> myfluid.viscosity.value.set_state(1.03e-3)
