Performance Issue

[lucric98]

The computational speed of the exact same workflow in Fluent GUI and using the Python API is approximately 50 times slower, despite yielding the same results. The entire workflow consists of both mesh generation and solution computation.
All the single steps, including:

• geometry import
• Mesh surface generation
• Mesh volume generation
• Boundary layers addition
• Local refinement regions
• Application of the solution settings to the mesh
• Solution computation
  The problem we are considering is a simple single fluid in laminar flow moving around a sphere inside a cylinder.
  Fluent: 2025R1 (Student Version),
  PyFluent: 0.33.0
  Python3.11.9
  Are we doing something wrong?

@lucric98 Thank you for submitting this issue.

• Is the slowdown associated with any particular stage (e.g., iterate(...), meshing, post-processing), or is it more evenly distributed across the workflow?

• Are you able to reproduce a similar slowdown using any of the shared Ansys example files (such as the one below), or would we need access to your specific project file (Disegno1_sfera.pmdb) to investigate?

from ansys.fluent.core.examples.downloads import download_file

def exhaust_system_geometry_filename():
    return download_file(
        file_name="exhaust_system.fmd", directory="pyfluent/exhaust_system"
    )

This will help us narrow down whether the issue is workflow-specific or linked to that particular model.

[lucric98]

Thanks for your help. We tried to reproduce the error with the geometry you linked, but seems like we cannot work with that file format.
Error: Faceted formats, like '.stl', '.tgf' and 'fmd' are not yet supported.

Error Object: #f

So we tried with another available .pmdb (mixing_elbow.pmdb) file and made the comparison between GUI and pyfluent. GUI is about 50 times faster in all steps.

complete_framework.wft Above you can see the timing (it takes few seconds in total) and the related workflow file. Below you can see python code and timings. Code has been generated with the help of a journal python transcript in GUI and slight modifications, mainly workflow.watertight() explicit calling, details regarding decribe the geometry and removing globals which do not seem to work for my case: instead I call workflow.workflow every time, which can be the origin of the issue, but I don't know how else I can make it run.

Hi @lucric98 Thank you for the update.

Could you please share more detailed timing data to help us pinpoint the bottleneck?
For each major task, it would be very useful to know:

• t₀ — When the PyFluent API method is called.

• t₁ — When Fluent starts processing that task (as seen in Fluent logs).

• t₂ — When Fluent finishes the task (again from Fluent logs).

• t₃ — When PyFluent returns control to the caller.

This breakdown will clarify how much time is spent:

• Inside PyFluent (Python layer)

• In the network or RPC

• Actually computing in Fluent.

With this info we can see whether the slowdown is due to client-side overhead, RPC latency, or Fluent’s own performance. Thanks!

[lucric98]

We tried to log all possible timestamps. If this is not enough, please modify the code we previously posted so that we can rerun it.
