Nodal Load

A nested class within Load used to create nodal loads.

Constructor

Load.Nodal(node, load_case, load_group = "", FX = 0, FY = 0, FZ = 0, MX = 0, MY = 0, MZ = 0, id = "")

Creates nodal loads (forces and moments) at specified nodes.

Parameters

  • node: Node ID where load is applied
  • load_case: Name of the load case
  • load_group (default=""): Load group name
  • FX, FY, FZ (default=0): Force components in X, Y, Z directions
  • MX, MY, MZ (default=0): Moment components about X, Y, Z axes
  • id (default=""): Manual ID assignment (auto-assigned if empty)

Object Attributes

  • NODE (int): The node number where the load is applied.
  • LCN (str): The name of the load case.
  • LDGR (str): The name of the load group.
  • FX (float): Force in the global X direction.
  • FY (float): Force in the global Y direction.
  • FZ (float): Force in the global Z direction.
  • MX (float): Moment about the global X axis.
  • MY (float): Moment about the global Y axis.
  • MZ (float): Moment about the global Z axis.
  • ID (int): The ID of the nodal load entry.

Methods

json

Returns JSON representation of all nodal loads.

nl1 = Load.Nodal(101, "Live Load", FZ=-50)
print(Load.Nodal.json())

create

Sends nodal loads to Civil NX.

Load.Nodal.create()

get

Fetches nodal loads from Civil NX.

print(Load.Nodal.get())

sync

Synchronizes nodal loads from Civil NX.

Load.Nodal.sync()

delete

Deletes all nodal loads from both Python and Civil NX.

Load.Nodal.delete()

Examples

#Nodal Load Example
for i in range(2):
    Node(i*10,0,0)
    Node.create()

Element.Beam(1,2)
Element.create()

#Load Case
Load_Case("L","Nodal Load")
Load_Case.create()

#Define Nodal Load

Load.Nodal(1,"Nodal Load","",FX=100,FY=200,FZ=-50,id=1)
Load.Nodal(2,"Nodal Load","",MX=10,MY=20,MZ=-5,id=2)
Load.Nodal.create()
