Boundary

The module provides functionality to create, manage, and synchronize boundary conditions including supports, elastic links, and rigid links in the model.

Note.

All the codes below assumes the initial import and MAPI Key definition.

from midas_civil import *
MAPI_KEY('eyJ1ciI6InN1bWl0QG1pZGFzaXQuY29tIiwicmciO252k81571d')

Methods

Boundary.create

Creates all defined boundary conditions (Supports, Elastic Links, Rigid Links, Points springs and Multi-Linear functions) in Civil NX.

Boundary.create()

Boundary.delete

Deletes all boundary conditions (Supports, Elastic Links, Rigid Links, Points springs and Multi-Linear functions) from both Python and Civil NX.

Boundary.delete()

Boundary.sync

Synchronizes all boundary conditions (Supports, Elastic Links, Rigid Links, Points springs and Multi-Linear functions) from Civil NX to Python.

Boundary.sync()

Complete Example
