Load and use surface to create imprint surface

Question

Dear support,

I am sent here after posting my problem in github and the support there couldn't give me a solution. The issue that was closed was the following: https://github.com/ansys/pyfluent/issues/4884#issuecomment-3851877585

I am trying to create an imprint surface by using a similar method with TUI commands : https://innovationspace.ansys.com/courses/courses/topics-in-general-post-processing-using-ansys-fluent-ii/lessons/loading-and-imprinting-surfaces-using-tui-commands/

I've managed to read the geometry that I wand to load using

session.settings.mesh.surface_mesh.read(file_name=stl2load, unit='m')

I can manually select the surface and create the imprint surface but it is imported with a Fluent default name which i don't know how to query using pyfluent. Once I know the name of the surface I can easily create the imprint using:

session_imprint_surf = session.settings.results.surfaces.imprint_surface

session_imprint_surf.create('surf_imprint')

surf_imprint_state = session_imprint_surf['surf_imprint'].get_state()

surf_imprint_state['name'] = 'surf_imprint'

surf_imprint_state['surface'] =  'surface_name' # <--- unkown when loading with surface_mesh.read()

surf_imprint_state['zones']  = ['fluid']

session_plane_surf['surf_imprint'].set_state(surf_imprint_state)

My question here is: How can I import a geometry and rename it to use it in postprocessing?

Hello @CesarAero,

Both the Pyfluent settings API and the TUI does not possess the information of the imported surfaces before imprinting it in Fluent. The naming convention seems to follow a set rule where the surfaces take the name "default-wall" as prefix. The names after the first file follows the same convention with a number added to the end along with a dot. Consider three different stl files imported separately using the surface_mesh.read command. The names of the imported surfaces would be as follows: default-wall, default-wall.1, default-wall.2

To conclude knowing the order of import or keeping track of this import using a counter should help in identifying the default name provided by Fluent to be used in an automation script.
