🐞 Description of the bug

When trying to run any of the examples provided on you get the following error:

Traceback (most recent call last):
  File "C:\Users\Abdulla\PycharmProjects\MiscProjects\pyansys_testing\example_template.py", line 21, in <module>

The issue seems to be cause by a typo in

pyprimemesh/src/ansys/meshing/prime/graphics/plotter.py

Lines 334 to 341 in ef07c44

	if plottable_object is not None:
	self.plot(plottable_object, name_filter=name_filter, scope=scope, **plotting_options)
	self._backend.show(
	object=plottable_object,
	screenshot=screenshot,
	name_filter=name_filter,
	**plotting_options,
	)

object=plottable_object should be plottable_object=plottable_object

📝 Steps to reproduce

run the following code:

import ansys.meshing.prime as prime
from ansys.meshing.prime.graphics import PrimePlotter

prime_client = prime.launch_prime()
model = prime_client.model

mesh_util = prime.lucid.Mesh(model=model)

mixing_elbow = prime.examples.download_elbow_fmd()
mesh_util.read(mixing_elbow)

mesh_util.surface_mesh(min_size=5, max_size=20)
mesh_util.volume_mesh(
    volume_fill_type=prime.VolumeFillType.POLY,
    prism_surface_expression="* !inlet !outlet",
    prism_layers=3,
)

display = PrimePlotter()
display.plot(model)
display.show()


prime_client.exit()

Hi @Abdullah-Azbah,

There is a 1to1 compatibility between client server versions. Please see the compatibility table here. For server 24R1 you should be using client version 0.5.X. Also please note there has been some changes to the graphics since this time and the API from that version has been deprecated.

Please also refer to the corresponding examples from the 0.5.X release to account for this change here.

I hope this helps!

Thanks

I also observed this issue in my environment, I believe it is an actual bug in the Graphics class @waltersma . I fixed it in #1063 but I closed that PR because I didn't need the rest of the implementation. I'll open another one with this fix.
