Get region name from point

Question

Dear support,

I am trying to automate a workflow where I need to rename the 3 fluid zones. However Fluent assigns a default name which I don't know in advance and even if for this case it is easy to guess, I would need to set my own names for more complex simulation cases:

I have a list of points with their coordinates which are inside of each volumetric region:

vol_inlet  = {  "X": -0.2,  "Y": 0.0, "Z": 0.0}

vol_radiator = { "X": -0.01, "Y": 0.0, "Z": 0.0}

vol_outlet = {  "X": -0.8,  "Y": 0.0, "Z": 0.0}

Is there any method that by inserting the coordinates of a point you can get if the point is within a closed region and get its name or to know if the point is outside the computational domain?

Thank you in advance!

That was indeed my missing argument, thanks!

Hello @CesarAero ,

I think you are missing an argument in the compute command which answers the question whether to reset names or not. I have tried the same command with 5 arguments, and it works for me.

meshing.tui.objects.volumetric_regions.compute("zone3cubes",'yes','mp1','()','yes')

Could you please check if the number of arguments are right once.

Hello @Vishal M,

After generating the surface mesh task (which generates the first mesh  object, named 'geom_surf'), I have used the following command to generate the material point:

session.tui.material_point.create_material_point('fluid_interior', -200, 2000.0, 200.0)

And then the following command to compute the zones pointing at the generated mesh object and the created material point:

session.tui.objects.volumetric_regions.compute('geom_surf', 'yes', 'fluid_interior', [])

However as you can se below, the commands do not lead to an error but the volumetric region isn't renamed and the material point isn't correctly assigned:

I am fully sure that my point is inside the domain but I have also tried with the coordinates of the default material point and it doesn't work neither:
