Scripting reference

Dina Hansen — Mon, 27 Apr 2020 09:31:23 GMT

Hi,

I have a question regarding the scripting reference in PLAXIS 2D CONNECT Edition V20:

https://www.plaxis.com/support/python-scripts/scripting-reference-and-how-to-use-it/

Is this scripting reference available as a PDF somewhere? I have PLAXIS 2018, and I do not have access to the scripting reference in PLAXIS.

Best regards,

Dina Hansen

Python scripting for beginners

Tomasz Daktera — Wed, 21 Oct 2020 07:50:32 GMT

Hello everyone,

I am a complete beginner with Python as well as the Python scripting for Plaxis use.

I have searched through the web and the Bentley Communities and I couldn't find any topic related to basic scripting such as drawing simple geometries and a simple use of Python in general.

Therefore my discussion topic for beginners.

My first question is (very basic... I know, but I have no clue how to deal with it...)

Why does my script doesn't work (Plaxis 2D) ?

from plxscripting.easy import *
s_i, g_i = new_server('localhost', 10000, password='>$viK!uhVhx9PB8Ss')

g_i.gotostructures()

x_min = -10
x_max = 10
y_min = -10
y_max = 10

boundaries =[]
boundaries.append([x_min,y_min])
boundaries.append([x_max,y_min])
boundaries.append([x_max,y_max])
boundaries.append([x_min,y_max])

g_i.polygon(*boundaries)

The error is the following (line 17 is g.i.polygon(*boundaries))

File "testpython1.py", line 17, in <module>
g.i.polygon(*boundaries)
NameError: name 'g' is not defined

Thanks for any tips,

EDIT : I found the error. Syntax error.

Unable to assign platemat properties in commands runner

Tomasz Daktera — Tue, 20 Oct 2020 11:14:07 GMT

Hello,

I am unable to assign properties to my plate by the commands runner.

If I run only that : _platemat "MaterialName" "Paroi gauche" "MaterialNumber" 0 " IsIsotropic" True "PreventPunching" True "EA" 20000000 "EI" 1666667 "nu" 0.2 "w" 0.15

It tells me :

Normal stiffness is zero!
Enter proper EA value.

I think those parameters (EA, EI, nu, w) should be enough as it calculates automatically the thickness of the plate right?

thanks for any help ...

Setting the material of a soil with command line

Tomasz Daktera — Mon, 19 Oct 2020 12:48:44 GMT

Hello,

My question is probably obvious - but I haven't found the answer on the forum.

I would like to create a soil material with the command line.

How can I do that ?

I found the following :

soilmat "Name" "SoilMat1" "MaterialName" "<NameInDBList>" "SoilModel" 2 "Gref" 1250

I added "Cref" 50 to that which allows me to set a cohesion in the Mohr Coulomb soil model soil.

What are the names of the other variables like the friction angle, moduli, Rinter etc. ? Where could I find a complete list for all soil models ?

Many thanks,

Tomasz
