sim-plugin-fluent 0.2.0

Ansys Fluent (PyFluent) driver and bundled skill for sim

sim-plugin-fluent

Ansys Fluent plugin for sim, built on PyFluent. It provides a live-session driver, Fluent-focused inspect targets, artifact classification, and a bundled agent skill for choosing between live sim sessions, direct PyFluent scripts, and file-side artifact review.

Install

uv pip install sim-plugin-fluent

Check that sim can discover Fluent:

sim check fluent

Live Session Quickstart

sim connect --solver fluent --mode solver --ui-mode no_gui \
  --driver-option dimension=3 \
  --driver-option precision=double \
  --driver-option processor_count=2

sim inspect session.versions
sim inspect session.health
sim inspect fluent.files

sim exec --label smoke --code "_result = {'status': 'ok'}"
sim inspect last.result
sim disconnect

Direct PyFluent Quickstart

from ansys.fluent.core import launch_fluent

solver = launch_fluent(mode="solver", ui_mode="no_gui", precision="double")
try:
    solver.settings.file.read_case(file_name="case.cas.h5")
    solver.solution.initialization.hybrid_initialize()
    solver.solution.run_calculation.iterate(iter_count=10)
finally:
    solver.exit()
