Hello,

I'm trying to use PyFluent to modify a already existing case :

%matplotlib
import ansys.fluent.core as pyfluent

solver = pyfluent.launch_fluent(
    precision="double",
    version="2d",
    processor_count=10,
    mode="solver",
    show_gui='True'
)

solver.file.read(file_type="case", file_name="example.cas.h5")

solver.tui.define.boundary_conditions.list_zones

inle = solver.setup.boundary_conditions.mass_flow_inlet['inlet']
inlet.mass_flow = 0.01

solver.file.write(
    file_type="case",
    file_name="example.cas.h5",
)

solver.tui.define.parameters.enable_in_TUI("yes")

But when I try to change an input parameter :

solver.tui.define.parameters.input_parameters.advance.use_in("udf_size", "htc_ext", 20)

I obtain :

invalid command [udf_size]

Error: wta(2nd) to string_eq
Error Object: #f

and why I try to use the TUI commande :

define parameters input-parameters advance use-in udf-side htc_ext set 0

It didn't work either :

Error: eval: unbound variable
Error: 'htc_ext'is predefined expression. Please change name.
Error Object: #f

Is there a way to run TUI code directly in a jupyter notebook or a command to update existing Pyfluent parameters?

I found the command for Python:

solver.tui.define.parameters.input_parameters.edit("name", "new_name", value)
