Error with win32com and Maxwell2D project: code previously working now fails

Lucie

Hello,

I have been using the following Python script (via win32com.client) to create a simple design in Ansys Electronics Desktop – Maxwell 2D. It was working correctly a few weeks ago, but now it returns an error when trying to open or create the project.

I’m wondering:

• Has there been an update to Electronics Desktop or Maxwell that could explain this behavior?
• Or do you see any issue in my code that could now cause this?

Here is a simplified version of the code that used to work:

import win32com.client

project_name = "Maxwell2Design_Test2Wires"
software = "Ansoft.ElectronicsDesktop"

oAnsoftApp = win32com.client.Dispatch(software)
oDesktop = oAnsoftApp.GetAppDesktop()

def create_project(design_type, project_name, solution_type, oDesktop):
    oProject = oDesktop.NewProject()
    oProject.InsertDesign(design_type, project_name, solution_type, "")
    return oProject

def get_or_create_project(project_name, design_type, solution_type, oDesktop):
    for project in oDesktop.GetProjects():
        if project.GetName() == project_name:
            return project
    return create_project(design_type, project_name, solution_type, oDesktop)

oProject = get_or_create_project(project_name, "Maxwell 2D", "Electrostatic", oDesktop)
oDesign = oProject.SetActiveDesign(project_name)
oEditor = oDesign.SetActiveEditor("3D Modeler")

oEditor.CreateRectangle(
    [
        "NAME:RectangleParameters",
        "IsCovered:=", True,
        "XStart:=", "2mm",
        "YStart:=", "2mm",
        "ZStart:=", "0mm",
        "Width:=", "2mm",
        "Height:=", "2mm",
        "WhichAxis:=", "Z"
    ],
    [
        "NAME:Attributes",
        "Name:=", "test",
        "Color:=", "255, 165, 0",
        "Transparency:=", 0.85,
        "PartCoordinateSystem:=", "Global",
        "MaterialValue:=", "\"vacuum\"",
        "SolveInside:=", True
    ]
