RE: Change variable in a loop

Hello Zakaria,

As we are the PLAXIS forum I will focus mainly on the PLAXIS side and let you sort out the best way to do this with your Python script.

Based on what I read, I assume that seeing no results means that the PLAXIS command line has no commands executed either. That might be the case as I see that in your last line, the PLAXIS Python command is within quotation marks (' ') making it a string.

Instead, the command has to pass directly to the scripting layer and especially the PLAXIS object itself. Via the .format() this comes as a string making it different to target the PLAXIS object SurfaceLoad_19 or the string 'SurfaceLoad_19'. I hope that this is clear now.

So, a way to achieve that is to use the getattr() function that PLAXIS offers. With this function, you provide a string, and you get the PLAXIS object. An example is:

srfload = 'SurfaceLoad_1_1'

surface_load_obj = getattr(g_i, srfload)

surface_load_obj.sigz[g_i.Phases[-1]] = -10

The above code should do the trick in helping you pass text as a string to PLAXIS objects and then be able to access them as commands.

That means that your last command should not be a string, otherwise, PLAXIS will not execute anything.
