Saving graphics elements using the pyFLUENT Graphics class - Pictures

[som1197]

I wanted to save pictures of a scene for different states as shown in the code below. It only works if I enable scene_test.display(). In the background the GUI internally sets the camera according to the state and then saves the picture. This happens even without the GUI. However, it adds a lot of run time to the code. Is there a way to make this process faster?

import ansys.fluent.core as pyfluent
session = pyfluent.launch_fluent(precision="double", processor_count=16, dimension = None, ui_mode="gui")

import_filename = r"..\file_name.cas.h5"
session.file.read_case_data(file_name = import_filename )

# Define the configurations
configurations = [
    "state_custom_y-10_z-5", "state_custom_y-10_z-2.5", "state_custom_y-10_z0", "state_custom_y-10_z2.5", "state_custom_y-10_z5",
    "state_custom_y-5_z-5", "state_custom_y-5_z-2.5", "state_custom_y-5_z0", "state_custom_y-5_z2.5", "state_custom_y-5_z5",
    "state_custom_y0_z-5", "state_custom_y0_z-2.5", "state_custom_y0_z0", "state_custom_y0_z2.5", "state_custom_y0_z5",
    "state_custom_y5_z-5", "state_custom_y5_z-2.5", "state_custom_y5_z0", "state_custom_y5_z2.5", "state_custom_y5_z5",
    "state_custom_y10_z-5", "state_custom_y10_z-2.5", "state_custom_y10_z0", "state_custom_y10_z2.5", "state_custom_y10_z5"
]

# Set the graphics resolution
graphics = session.settings.results.graphics
if graphics.picture.use_window_resolution.is_active():
    graphics.picture.use_window_resolution = True
# graphics.picture.x_resolution = 3840
# graphics.picture.y_resolution = 2880

# Create the scene
session.results.scene["scene-test-vanes"] = {}
session.results.scene["scene-test-vanes"].title = "scene-test-vanes"
session.results.scene["scene-test-vanes"].graphics_objects["mesh-1"] = {}
session.results.scene["scene-test-vanes"].graphics_objects["mesh-2"] = {}
session.results.scene["scene-test-vanes"].graphics_objects["mesh-3"] = {}
session.results.scene["scene-test-vanes"].graphics_objects["mesh-4"] = {}
session.results.scene["scene-test-vanes"].graphics_objects["contour-ui-pd"] = {}

# Loop through each configuration and save the picture
for config in configurations:
    session.results.scene["scene-test-vanes"].display_state_name = config
    scene_test = session.results.scene["scene-test-vanes"]
    scene_test.display()
    file_name = rf"..\scene_{config}.png"
    graphics.picture.save_picture(file_name=file_name)

You could use PyFluent-Visualization as it supports saving pictures without displaying.
