Python get Structual element by Name

Question

Hi, 
 there is a script example to get the anchor forces out during several phases: 
 Output scripting example: get anchor force - PLAXIS | SOILVISION Wiki - PLAXIS | SOILVISION - Bentley Communities 
 the anchor is identified by its location (g_o.getresults(phase,g_o.ResultTypes.NodeToNodeAnchor.Y,'node') ) 
 is it possible to identify anchors or plates by its Name / Identification?

EXAMPLE: Plate 438 / [Plate_9_3] 
 thanks.

Dear Falko, 
 The getresults command supports an object name directly as a parameter. This means you can do the following: 
 g_o.getresults( g_o.NodeToNodeAnchors[0] , g_o.Phases[-1], g_o.ResultTypes.NodeToNodeAnchor.Y, 'node') 
 Therefore you can simply have a for-loop for each anchor and avoid collecting all data and then sorting them out. This can prove to be a better approach overall. 
 Currently most of the properties in the g_o.ResultTypes concern resulting values and not so much the name of objects, which is why you cannot find a property for the name.

Hello Falko, 
 This is a Python issue (not a PLAXIS one) in which you are simply confused about which variables to call in the print statement. 
 You do a for-loop over the lists that contain the results: X, Uxs, Uys 
 With this for-loop you use the internal variables: x, y, N 
 And when it comes to printing them you should use the internal ones and not the full lists. So, just replace the last command with the following and everything runs smoothly: 
 print("Plate @ x {}: horizDisp {:.2f} m vertSettlement {:.2f} m".format(x, y, N)) 
 In the future, it will be helpful to you to do a small debugging yourself as you could spot this problem by understanding the error message Python gives you. 
 It mentions a TypeError and an unsupported format string passed . This points to the {:.2f} which is the string formatting you do. For instance, by removing it you would get the command working but here is how it looks: 
 
 This is what triggered me to check what is actually passed to the string formating via the {}. And then you see that for every line you get the same, which is true, you get the full list as an object (PlxProxyObjectValues to be precise). 
 I hope that this helps (in the future, too). 
 
 For the record this is the correct one:

Hi Stefanos, 
 after digging in a bit: 
 I used the g_i.get_equivalent() method to get the Name of the plate and do some filtering on the results. 
 Thank You Stefanos.

Dear Zakaria, 
 I am missing some information here, which makes it difficult to give a straightforward answer. 
 I will give you nevertheless an approach you can use. 
 If you are working with PLAXIS Output and with the getresults (or any of the "results" commands) our approach is to use the syntax that supports providing the name of the plate already instead of collecting the results for all plates. So, for instance: 
 for plate_parent in g_o.Plates[:]:
 for plate_cut in plate_parent:
 print(plate_cut.Name)
 uy_per_plate_cut = g_o.getresults(plate_cut, g_o.Phases[-1], g_o.ResultTypes.Plate.Uy, 'node') 
 Note that the g_i.get_equivalent() is a function implemented by us to identify the equivalent object between modes in Input and between Input and Output. The case of the user above is different and I would recommend the approach I just described.
