Generate probe Graphics Annotations with Ansys Mechanical Scripting

Hello!

I can use the following Code Snippet script to create a single label at a specific X,Y,Z-location:

labels_manager = Graphics.LabelManager
result = Tree.FirstActiveObject
with Transaction():
    _old = labels_manager.GetObjectLabels(result)
    Graphics.LabelManager.DeleteLabels(_old)
    probe_label = labels_manager.CreateProbeLabel(result)
    point = Ansys.Mechanical.Graphics.Point([-142.835450,176.906526,105.497730],'mm')
    probe_label.Scoping.XYZ = point
    #probe_label.Note = "NULL"
    probe_label.Color = Ansys.ACT.Common.Graphics.Color(red=255, green=255, blue=255, alpha=100)

I want to make this stronger by being able to loop through a set of points in an array and assign a label to each one. How can I edit the snippet to do this?

Hi ! This example should help: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v241/en/act_script/act_script_examples_hot_spot.html

Thanks! The Scripting in Mechanical Guide was weirdly hard for me to find.

I also found this:

A really good guide which helped me create a working script.

Hello Team, I have a list of nodes on which I have created temperature annotations for one load case.
I want to re generate these annotations for other load steps. How to do this using script.

@ARF , I am not sure I fully understand your question. If you have created the temperature labels via script, it's just a matter of replaying the script to generate the labels again. If you have a list of nodes, the example I shared above shows how to create a label on a specific node. You'll have to generate several temperature plots for the load cases you're interested in, and you can loop on those plots to generate the labels within the script.

@Pernelle Marone-Hitz Sorry for the confusion. Let me add more details.

I have created the labels manually using the probe tool for load case-1. Now when you create these labels, There is a window in the bottom called "Graphics Annotations" where you can find all the info related to labels like Node numbers etc. That is why I said " I have the list of nodes where I want to create the labels"

Now, when I create the result for Load case-2 I have again manually pick (20-25 times per load case) all the nodes to create labels because ANSYS does not re-generate the previously created labels when you retrieve the temp. results for load case-2. I wanted to do it using a script.

Let me know your thoughts, Thanks

@Ayush Kumar can you provide some insight.

@ARF Thanks for the clarification. This scenario is not ideal, as, if I understand correctly, you can only get the node IDs from the first load case through manual picking. I was hoping you would have another way of getting the node IDs so that you could use a fully scripted approach. Perhaps you would actually have a way of identifying those nodes through script (ie if you are looking for local maximas, this is something that could be scripted).
Anyway, with your current approach, you can get a list of the probes through labelsForRes = Graphics.LabelManager.GetObjectLabels(resultObject) where resultObject is the result object you have created. For each item of this list, you can access the node Id through label_i.Scoping.Node. You can then use this node Id to create the probes for the new result set, through:

probeLabel = Graphics.LabelManager.CreateProbeLabel(NewResult)
probeLabel.Scoping.Node = label_i.Scoping.Node

Hope this helps !

@Pernelle Marone-Hitz I tried to run the script. but i am getting some error.

I am new to the scripting world. Can you suggest what is the issue here ?

ARF

Also, I don't get the LabelManager option in the auto complete.

Pernelle Marone-Hitz

@ARF , for the first problem, it is just a typo: you used CreatProbeLabel, it should be CreateProbeLabel ("E" at the end of "creatE").
The issue with the autocomplete is known, to get all the possible methods on an object, the best way is to use dir(object) .

Below script worked for me, Here list is the list of nodes.

for i in list:
resultObject=ExtAPI.DataModel.GetObjectsByName('Temperature 6')[0]
probe=Graphics.LabelManager.CreateProbeLabel(resultObject)
probe.Scoping.Node= i
