Fluid swirl#

This example illustrates a one-way data transfer from a SCDT file to Fluent, using System Coupling. Fluent solves a simple steady fluid flow problem, where the flow is affected by the momentum sources defined in the SCDT file.

Problem description

Fluid flow problem consists of the water flowing through the pipe.

../../_images/fluid_swirl_setup.png

The SCDT file will be generated that consists of a cloud of points overlapping the fluid domain. At each point, the force density value is defined, with force acting along the flow cross-section, always in a counter-clockwise direction (if looking from the inlet to the outlet).

System Coupling is used to map the data from the cloud of points defined in the SCDT file onto Fluent mesh. The force values are then transferred into Fluent and Fluent solves the resulting fluid flow problem, where the fluid is influenced by the provided forces. As a result, the swirl is induced in the fluid flow.

Import modules, download files, launch products#

Setting up this example consists of performing imports, downloading the input file, and launching the required products.

Perform required imports#

Import the ansys-systemcoupling-core package and other required packages.

import math

import ansys.fluent.core as pyfluent

import ansys.systemcoupling.core as pysystemcoupling
from ansys.systemcoupling.core import examples

Download input files#

Download the case file for Fluent and the FMU file.

fluent_cas_file = examples.download_file(
    "water_pipe_flow.cas.h5", "pysystem-coupling/fluid-swirl"
)

Launch products#

Launch a remote Fluent and System Coupling instances and return client objects that allows you to interact with these products via an API exposed into the current Python environment.

Note

Fluent version greater than 24.1 is required. To specify Fluent version explicitly when launching Fluent, use product_version argument to the launch_fluent function, for example pyfluent.launch_fluent(product_version="24.2.0")

fluent = pyfluent.launch_fluent(start_transcript=True, processor_count=4)
# XXX Temporary start_output=True while investigating issue
syc = pysystemcoupling.launch(start_output=True)
pyfluent.launcher WARNING: Configuring Fluent container to mount to /home/runner/work/pysystem-coupling/pysystem-coupling/examples/00-systemcoupling, with this path available as /home/container/workdir for the Fluent session running inside the container.

Setup#

The setup consists of setting up the the fluids analysis, generating the SCDT file, and setting up the coupled analysis.

Generate the SCDT file#

The following script generates a simple comma-separated file with points defined along the fluid domain. Six columns of data will be written: x, y, z coordinate values, followed by x-, y-, and z-components of the force density field. The number of points can be adjusted by naxial, ncirc, and nrad parameter values. The magnitude of the force (defined in N/m^3) can be adjusted by force_mag parameter value.

def create_source_file(file_name):
    force_mag = 5.0
    naxial = 33
    ncirc = 10
    nrad = 20
    radius = 0.025
    with open(file_name, "w") as f:
        for xi in range(naxial):
            x = (1.0 - 0.0) * xi / (naxial - 1)
            for ti in range(ncirc):
                theta = 2.0 * math.pi * ti / ncirc
                for ri in range(nrad):
                    r = radius * (ri + 1) / nrad
                    z = r * math.cos(theta)
                    y = r * math.sin(theta)
                    fx = 0.0
                    fy = force_mag * math.sin(theta + 0.5 * math.pi)
                    fz = force_mag * math.cos(theta + 0.5 * math.pi)
                    f.write(f"{x}, {y}, {z}, {fx}, {fy}, {fz}\n")


src_file_base_name = "source"
src_file_name = f"{src_file_base_name}.scdt"
create_source_file(src_file_name)

Set up the coupled analysis#

System Coupling setup involves adding the SCDT file and Fluent solver session as participants, adding coupled interfaces and data transfers, and setting other coupled analysis properties.

Add participants

source_name = syc.setup.add_participant(input_file=src_file_name)
fluid_name = syc.setup.add_participant(participant_session=fluent)
Feature already enabled.

Add a coupling interface and data transfers#

# Add a coupling interface for SCDT file -> Fluent
interface_name = syc.setup.add_interface(
    side_one_participant=source_name,
    side_one_regions=[src_file_base_name],
    side_two_participant=fluid_name,
    side_two_regions=["tube_solid"],
)

# Add force data transfer.
# Use System Coupling expression to combine force field
# components in the SCDT file into a vector.
# System Coupling will automatically convert force density
# values on the source (defined in [N/m^3]) to force
# values on the target (defined in [N]).
syc.setup.add_data_transfer(
    interface=interface_name,
    target_side="Two",
    target_variable="lorentz-force",
    value="vector(Variable1 * 1.0 [N], Variable2 * 1.0 [N], Variable3 * 1.0 [N])",
)
