Most probably through PyWorkbench... transferring the issue to their repo.

this link shows pyansys with python flask do the the job I want to do with .romz file

but I don't know how to load .romz file in a web in pyansys

@RobPasMue The question has nothing to do with PyWorkbench. Sorry!

[RobPasMue]

@kewudu what Ansys product do you want to read this file from?

[kewudu]

Ansys product do you want to read this file

we want not to use Ansys product to read .romz file, we want to read .romz file by pyansys or other SDK and display the .romz model in the web

@RobPasMue - I think it's a Fluent file format.

@RobPasMue - I think it's a Fluent file format.

yes, .romz file is a Fluent file format, https://ansyshelp.ansys.com/public/account/secured?returnurl=/Views/Secured/corp/v242/en/flu_ug/flu_ug_rom.html is the description for .romz file

[RobPasMue]

Transferring to the PyFluent repository in case they have a standalone .romz reader as part of their library but, from my knowledge... I doubt this is possible. You would need to read it using Ansys Fluent most probably (through PyFluent).

@ansys/pyfluent-maintainers could you help this user out?

[seanpearsonuk]

Hi @RobPasMue. Not here. Have you checked PyTwin? I don't think they have such a thing in Python right now but perhaps in the future?

[RobPasMue]

Good point -- pinging the @ansys/pytwin-owners team for help/support

[RobPasMue]

Oh... I just realized nobody apart from @MaxJPRey is in that team! Pinging @chrpetre and @lboucin for support!

@RobPasMue @seanpearsonuk - romz file are ROM generated from Workbench/DX that can be evaluated/post processed in Fluent as far as I know, or exported as FMU

Pytwin cannot directly handle romz files, and there is no plan for that (as this is a Workbench/Fluent feature).

However and FYI @kewudu, Twin Builder has equivalent ROMs workflows that can be evaluated with Pytwin to realize similar use cases as the one described in this thread, see for examples https://twin.docs.pyansys.com/version/stable/examples/index.html#tbrom-evaluation-examples

@seanpearsonuk @RobPasMue @kewudu to add on @chrpetre answer, let me point out there is automated way to convert snapshot file generated from Workbench/DesignXplorer/3DROM to Twin Builder/Static ROM. That can be done in few clicks as explained on below slide. I've double check this workflow is still operational in Ansys/Workbench 25R1

FYI. DesignXplorer is in maintenance mode for several years now and its capabilities will start to be depreciated in Ansys/Workbench 25R2.
Also FYI @kewudu you might be interested to learn what can be done with PyTwin and Twin Builder ROM capabilities (including ROM evaluation in Web App) watching this webinar: https://www.ansys.com/webinars/seamless-digital-twin-deployment-with-ansys-pytwin-leveraging-roms
