Fluent 2023R1: solution.initialization.patch.calculate_patch is inactive and cannot be used

Bodhi0Tree

I am using Fluent 2023R1 and trying to perform a temperature patch on the fluid domain to initialize the combustion simulation. I have already performed standard initialization, but the calculate_patch command remains inactive.

When I run:
python
solver.solution.initialization.patch.calculate_patch(
domain="Fluid",
cell_zones=["fluid"],
variable="temperature",
value=2000
)

I get the following error:
ansys.fluent.core.solver.flobject.InactiveObjectError: '.solution.initialization.patch.calculate_patch' is currently inactive.

The help documentation shows command_names = ['calculate_patch'] under patch, but the command is never active.

This is blocking my ability to initialize the temperature field for combustion simulations. Please advise on how to activate the patch command or provide a working alternative.

Hello @Bodhi0Tree

Ideally the patch command should be active after initialization. The issue why the patch does not work is still unclear.

You can use the following TUI based work around to go ahead with the patch

solver.tui.solve.patch("fluid","()","temperature",500)

When a settings API command is not active or not exposed, you can resort to using the corresponding TUI based commands. The following documentation explains how to convert TUI commands to respective Pyfluent commands

I hope this information helps you.
