Extract results over a chosen interface Python

Okay I understand. I've been avoiding this but I see that I have no choice. Thank you Stefanos, have a good day.

Hello again,

I meant that you should loop over all Interfaces.

This means that you would have first PositiveInterface_1_1, PositiveInterface_1_2 and so on and then NegativeInterface_1_1, NegativeInterface_1_2 and so on. There you can do your filtering.

That would be the first parameter of the getresults command as noted in the examples of the Command Reference, too.

Thanks you Stefanos. I thought of filtering by name but I couldn't get the name for each interface. It works when I call results for one Interface (PositiveInterface_1 for example) but when I call all the interfaces, I get "Interfaces". Do you have a suggestion ?

Dear Zakaria,

There is no distinction between positive or negative interfaces in PLAXIS. They are all Interfaces for the results and the calculation kernel. The distinction is when it comes to determining the side for visualisation purposes.

I would advise you instead of trying to get the results per Interface object so you can filter them based on the names which include the word Positive, instead.

Hello Stefanos Papavasileiou
Is there a way to get all the positive interfaces ? g_o.Interfaces works, but i'm looking for something like g_o.PositiveInterfaces
Thank you

Great! I am glad to hear that!

Thanks Stefanos! It was the way i was trying to set the phase, in my ebedded beam one i had an extra stage (the g_o.Phases stage), but had forgotten to use that in this one, so i was just trying to use my phase as "8". All sorted now!

Dear Maggie,

Have you checked our documentation? You can find it under Help>Command reference>Output commands>getresults.

You can find a couple of alternatives (examples) of the syntax of the command that includes any object, e.g., embedded beam or in your case, interface.

The same for scripting as you are writing a Python script. You can find it under Help>Scripting reference>Output>getresults.

The one thing I notice in your case is that even though the structure of the command is correct, apparently the variable "interface" is pointing to a number (=8). So the error message is actually correct, something in your specified parameters is not as expected.
Therefore, I think that somewhere in your script that variable is defined and it should have been, for example, g_o.PositiveInterface_8_1 and not it is just 8.

If you correct that part in your script then the command should work, which you can verify by running it first in the PLAXIS command line (use the PLAXIS syntax) or via the Interpreter (with Python):

getresults PositiveInterface_8_1 ResultTypes.Interface.InterfaceTotalNormalStress "node" # for example

interface = g_o.PositiveInterface_8_1 # for example
phase = g_o.Phases[-1] # for example
g_o.getresults(interface, phase, g_o.ResultTypes.Interface.InterfaceTotalNormalStress, 'node')
