Define materials

PyFluent supports using Solver TUI commands and Solver settings objects to define materials.

Use solver TUI commands

This example shows a comparison between the TUI command and the Python code for defining the fluid material being modelled on a cell zone.

TUI command

/define/materials elbow-fluid yes water-liquid no no no no 0 no 0 no 0 no 0 no 0 no 1 no no no no no

Python code

import ansys.fluent.core as pyfluent

solver = pyfluent.launch_fluent(precision="double", processor_count=2, mode="solver")
solver.tui.file.read_case("file.cas.h5")
solver.tui.define.materials.copy("fluid", "water-liquid")
solver.tui.define.boundary_conditions.fluid(
    "elbow-fluid",
    "yes",
    "water-liquid",
    "no",
    "no",
    "no",
    "no",
    "0",
    "no",
    "0",
    "no",
    "0",
    "no",
    "0",
    "no",
    "0",
    "no",
    "1",
    "no",
    "no",
    "no",
    "no",
    "no",
)

Use settings objects

This example shows how you use Solver settings objects to define materials.

Python code

solver.setup.materials.copy_database_material_by_name(type="fluid", name="water-liquid")
solver.setup.cell_zone_conditions.fluid["elbow-fluid"].material = "water-liquid"
