Description of the bug

The python file execute normally, and I convert it to an .exe file by pyinstaller. There are many errors when the .exe file executes, for example "Error occurred while coping file".

Steps To Reproduce

from ansys.aedt.core import Icepak
import csv

ipk = Icepak()

box = ipk.modeler.create_box([0, 0, 0], [5, 5, 1])

ipk.assign_solid_block(object_name=box.name, power_assignment='0.1W')

for face in ipk.modeler['Region'].faces:
    ipk.assign_free_opening(
        assignment=face.id,
        flow_type='Pressure'
    )


ipk.mesh.generate_mesh()

setup1 = ipk.create_setup()
setup1.props['Flow Regime'] = 'Laminar'
setup1.props['Convergence Criteria - Max Iterations'] = '100'
setup1.props['Convergence Criteria - Flow'] = '0.001'
setup1.props['Radiation Model'] = 'Discrete Ordinates Model'
setup1.props['Flow Iteration Per Radiation Iteration'] = '10'
setup1.props['ThetaDivision'] = '3'
setup1.props['PhiDivision'] = '3'
setup1.props['ThetaPixels'] = '3'
setup1.props['PhiPixels'] = '3'
setup1.props['Include Gravity'] = True


ipk.analyze()


with open(r'D:\test.csv', 'w', newline='') as f:
    writer = csv.writer(f)
    writer.writerow(['componentName', 'MaxTemperature'])
    maxTemp = ipk.post.get_temperature_extremum(
        assignment=box.name,
        max_min='Max',
        location='Volume'
    )
    maxTemp = round(maxTemp[1], 1)
    writer.writerow([box.name, maxTemp])

Do you encounter any issue in running the native code? If yes, what? If no, is there any reason why you think this is a pyAEDT issue?
Are you sure this is not an expected issue of using pyinstaller?

[chs513]

@lorenzovecchietti No issue in running the native code. Sorry, I'm not familiar with pyinstaller.

[lorenzovecchietti]

No problem. What I would check is if the initialization of AEDT works properly with pyinstaller. But bear in mind that I'm absoluterly not familiar too.

Also, if your need is just to make the script clickable you can consider:

• to integrate the call af the python script in some powershell script
• to add an extension inside aedt (if you installed pyaedt from the application)

@lorenzovecchietti Thanks for your reply.
