How can I get the node/vertex coordinates for defined springs in ANSYS Mechanical using scripting?

    Hello, I think you could take the Location coordinates from reference and mobile attachments

    Something like this should help you to start:

    AllSprings = ExtAPI.DataModel.GetObjectsByType(DataModelObjectCategory.Spring)

for spring in AllSprings:
    print("X Ref = ",spring.ReferenceXCoordinate)
    print("Y Ref = ",spring.ReferenceYCoordinate)
    print("Z Ref = ",spring.ReferenceZCoordinate)
    print("X Mob = ",spring.MobileXCoordinate)
    print("Y Mob = ",spring.MobileZCoordinate)
    print("Z Mob = ",spring.MobileYCoordinate)

    Best Regards

    Just to add that the above script also works for direct attachments on nodes or vertices.

    Hope this helps.

    Thank you for your kind reply. I have figured it out in a different way as the following:

    select Connections in the Tree

    sel = DataModel.GetObjectsByName('Connections')[0]

    select Springs under Connections

    a=sel.Children[0]
    springs=a.Children # Create a list of all the springs defined

    **Then ,you can use the following to write them to a csv file: **

    for spring in springs:
    ratio=spring.MobileYCoordinate.Value/spring.MobileXCoordinate.Value

    if spring.MobileXCoordinate.Value<0 and spring.MobileYCoordinate.Value>0:
        theta=atan(ratio)*180/3.1415926 + 180
    elif spring.MobileXCoordinate.Value<0 and spring.MobileYCoordinate.Value<0:
        theta=atan(ratio)*180/3.1415926 - 180
    else:
        theta=atan(ratio)*180/3.1415926

    formated_X='{:5.2f}'.format(spring.MobileXCoordinate.Value)
    formated_Y='{:5.2f}'.format(spring.MobileYCoordinate.Value)
    formated_theta='{:5.2f}'.format(theta)
    writer.writerow([spring.Name,formated_X,formated_Y,formated_theta])
