🐞 Description of the bug

I am using Ansys 2024 R2 and trying to programmatically generate needed linear stress results. I get two different results using the same code internally and externally. Specifically the external script does not create results sets.

In my project I record to click operations to generate the following.

solution_23 = DataModel.GetObjectById(23)
linearized_normal_stress_1680 = solution_23.AddLinearizedNormalStress()
path_849 = DataModel.GetObjectById(849)
linearized_normal_stress_1680.Path = path_849
linearized_normal_stress_1680.NormalOrientation = NormalOrientationType.YAxis
linearized_normal_stress_1680.Name = r"""SCL_YY"""
linearized_normal_stress_1680.EvaluateAllResults()
solution_23.CreateResultsAtAllSets(linearized_normal_stress_1680.ObjectId)
linearized_normal_stress_1680.EvaluateAllResults()

If I put this same script into a text file and execute it the results are not generated. The tree shows no change. Am I missing something simple? The primary portion is an exact copy of why Ansys Mechanical Generates so I am confused as to why it would not work.

import ansys.mechanical.core as mechanical

filename = ".\\demo-data\\cube_example_files\\dp0\\global\\MECH\\SYS.mechdb"

app = mechanical.App(str(filename))

app.update_globals(globals())
app.print_tree()

solution_23 = DataModel.GetObjectById(23)
linearized_normal_stress_1680 = solution_23.AddLinearizedNormalStress()
path_849 = DataModel.GetObjectById(849)
linearized_normal_stress_1680.Path = path_849
linearized_normal_stress_1680.NormalOrientation = NormalOrientationType.YAxis
linearized_normal_stress_1680.Name = r"""SCL_YY"""
linearized_normal_stress_1680.EvaluateAllResults()
solution_23.CreateResultsAtAllSets(linearized_normal_stress_1680.ObjectId)
linearized_normal_stress_1680.EvaluateAllResults()

app.print_tree(max_lines=-1)

It seems that the sets aren't being created because the data is not cleared but the data clear fails

@anthony-walker.

I tested with a simple model with same code but I am seeing no issues. May its specific to the file you are using. Could you please share the .mechdb files and script if possible? If you want to share directly, please email to pyansys.core@ansys.com with title "pymechanical issue 1002 requested files"
