NextFEM Python Scripting<\/h2>\n<\/td>\n<\/tr>\n

\n
Empower structural analysis with Python<\/h5>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

NextFEM APIs can be used with Python as well. This plugin helps developers in finding and testing every API instruction, directly in Designer and with immediate effect in the model.<\/p>\n

Integrated Python scripting<\/h3>\n

Integrated Python scripting can be started by the command Tools \/ Python scripting<\/em>. It is a web-powered Python scripting engine, able to run scripts and\/or code snippets directly from within the program. Below you can see it in action after this sample script<\/strong><\/a> has been run.<\/p>\n

\"\"<\/p>\n

Samples are available here<\/strong><\/a>.<\/p>\n

NextFEMpy Python package<\/h3>\n

We supply the NextFEMpy Python package, which is a NextFEM REST API wrapper in pure Python, to be used with NextFEM Designer or NextFEM Server. It is a complete set of REST API call, wrapped in Python functions, distinguishing between mandatory and optional arguments.<\/p>\n

If you’re looking for NextFEMpy source, look into \/nextfempy folder. If you’re looking for sample code using nextfempy, look into \/samples folder.<\/p>\n

\n
Installation instructions<\/h6>\n

<\/a>pip install nextfempy
\n<\/code><\/p>\n<\/div>\n

<\/div>\n
\n
Upgrading instructions<\/h6>\n

<\/a>pip install nextfempy --upgrade
\n<\/code><\/p>\n<\/div>\n

<\/div>\n
\n
Usage<\/h6>\n

<\/a>Before using with your local installation of NextFEM Designer, start the plugin REST API Server.<\/p>\n<\/div>\n

\n
from nextfempy import NextFEMrest\r\n# connect to local copy of NextFEM Designer\r\nnf=NextFEMapiREST.NextFEMrest()\r\n<\/code><\/pre>\n<\/div>\n
To handle a property:<\/p>\n
\n
nf.autoMassInX=False\r\nprint(str(nf.autoMassInX))\r\n<\/code><\/pre>\n<\/div>\n
To call a NextFEM API method:<\/p>\n
\n
nf.addOrModifyCustomData(\"test\",\"Test\")\r\nprint(nf.getCustomData(\"test\"))\r\n<\/code><\/pre>\n<\/div>\n
Python Console<\/h3>\n
The Python Console<\/em> in NextFEM Designer is accessible in the Plugin tab.<\/p>\n
\"\"<\/p>\n
This plugin works only with 64bit version of NextFEM Designer and needs Python3 64bit installed in system. Users must have Python available in the PATH environment variable.<\/p>\n
This plugin is formed by two boards:<\/p>\n
    \n
  1. a Linked board<\/strong> in which every API method affects the model and the viewport. This has Python syntax and some basic functions, but it\u2019s not a complete Python console. In the lower textbox, start typing \u201c\u201d and the available commands will be suggested, as well as their arguments. Arguments between \u201c<\u201d and \u201c>\u201d are optional. API reference can be recalled by pressing Open API reference<\/em>.<\/li>\n
  2. An External board<\/strong>, which is a complete Python terminal. The instance of API (always called nf<\/strong>) is not linked to the model here. You can export the model from linked to external board by the button Export model<\/em>.<\/li>\n<\/ol>\n
    The other controls in this form are associated to the ViewState<\/em> and undoOps<\/em> enumerator and with the resize<\/em> boolean variable as explained above.<\/p>\n","protected":false},"excerpt":{"rendered":"
