Description of the bug

I wanna convert the mnist pic into a 3D object. The pixel value equal the depth of the groove on the upper surface. So i create more than 100 vacuum cube that need unite. Same code It works well on Ansys EM 2021.2 and pyaedt v0.6.48. But recent i update to the Ansys EM 2023.2 and pyaedt v0.7.6, it's always returen error like "PyAEDT ERROR: Error in uniting objects." I tried unite less than 50 object, it works well. But as i unite more entire 132 object, the error shows. Please help me fix this problem. thanks.

Steps To Reproduce

X, y = mnist_data()

for z in range(1,3): projectname = str(os.path.join(root, "array"+str(z)+".aedt")) projects['project_' + str(z)] = Maxwell3d(projectname=projectname, designname="array" + str(z), close_on_exit=False, non_graphical=False) image = X[int(z)].reshape((28, 28)) / 255 aluminum_dimensions = [44, 44, 2] aluminumblock = projects['project' + str(z)].modeler.create_box([0, 0, 0], aluminum_dimensions, matname="steel_1008", name="test") for i in range(28): for j in range(28): if image[i, j] >= 0.5: airblock = projects['project' + str(z)].modeler.create_box([i 1.6, j 1.6, 2], [1.6, 1.6, -(image[i, j])], matname="Vacuum", name="airblock"+str(i)+str(j)) airlist = projects['project' + str(z)].modeler.get_objects_wstring("airblock") projects['project_' + str(z)].modeler.unite(air_list, True, False)_

projects['project_' + str(z)].modeler.subtract(["test"], ["airblock"], keepOriginals=False)

# projects['project_' + str(z)].modeler.create_region(0, True)
# projects['project_' + str(z)].analyze(blocking=False)

projects['project_1'].release_desktop(True, True)

@Andrew993-chang This should work, please share a script that can reproduce the issue, end-to-end. We do not know the returned value: X, y = mnist_data()

Thanks

@Samuelopez-ansys Please refer to the attachment and run the create_environment.py file. Thanks for_debug.zip

Hi @Andrew993-chang,

This is not a PyAEDT bug, I have run your code and it is an AEDT bug. In 2023, AEDT changed the CAD kernel, from ACIS to Parasolid, for that reason in 2022.1, you didn't have this issue. Please contact Ansys technical support with the model directly, because if you try to unite the boxes in the AEDT user interface, it will fail too, then it is not a scripting problem, it is an AEDT problem. I will close this issue.

Thanks, Samuel
