create local mesh

[KlausNeumaier]

Hi,
I am creating a local mesh by
mesh_region = ipk.mesh.assign_mesh_region(assignment = object_names, name=mesh_name)
The version is 2025R1
The error I get is :

[error] File XXX, line 543, in
[error] mesh_region = ipk.mesh.assign_mesh_region(assignment = object_names, name=mesh_name)
[error] AEDT API Error on create_subregion
[error] Last Electronics Desktop Message - [error] script macro error: abnormal script termination. ()
[error] Method arguments:
[error] padding_types = Percentage Offset
[error] assignment = [<ansys.aedt.core.modeler.cad.object_3d.Object3d object at 0x00000218A48A08D0>, <ansys.aedt.core.modeler.cad.object_3d.Object3d object at 0x00000218A488CCD0>]
[error] name = SubRegion_7FICCC

[error] 'nonetype' object has no attribute 'name' on create
[error] Last Electronics Desktop Message - [error] script macro error: abnormal script termination. ()

Any idea what's going wrong.
Thank you very much

Hi @KlausNeumaier,

please check that you pass a list of strings to assignment and not a list of object_3d.Object3d instances. As an example, this works:
ipk.mesh.assign_mesh_region(assignment = ["Box1"], name="testMeshRegion")

Also: you will get some warning messages in the message windows. It is a known bug (#5926), but the creation of the mesh region will be successful.

Hi Lorenzo,
using list of object names rather list of objects solved the issue.
Thank you for your help
