Time Dependent Link
Time-Dependent Material Link
The TDLink class links materials with their time-dependent properties (creep/shrinkage and compressive strength).
Class Attributes
TDLink.mats -> Dictionary of all material links.
Methods
json
Returns a JSON representation of all Time-Dependent Material Links defined in python.
print(TDLink.json())
# Output:
# {'Assign': {'1': {'TDMT_NAME': 'CS_M25', 'TDME_NAME': 'Comp_M25'}, ...}}
create
Sends material links to Civil NX using a PUT request.
TDLink.create()
get
Fetches material links from Civil NX and returns the JSON representation.
print(TDLink.get())
sync
Retrieves Time-Dependent Material Link data from Civil NX and rebuilds the internal dictionary.
TDLink.sync()
delete
Deletes all material links from both Python and Civil NX.
TDLink.delete()
Examples
# Link materials with their time-dependent properties
link1 = TDLink(1, "CS_M25", "Comp_M25") # Link material ID 1 with M25 properties
link2 = TDLink(2, "CS_C30", "Comp_C30") # Link material ID 2 with C30 properties
link3 = TDLink(3, "CS_M25", "") # Link material ID 3 with only creep/shrinkage
TDLink.create()

# Link materials with time-dependent properties
# Assuming materials with IDs 1, 2, 3 exist
link1 = TDLink(1, "CS_M25", "Comp_M25") # Link material 1 with M25 properties

link3 = TDLink(3, "CS_M40", "Comp_M40") # Link material 3 with M40 properties
# Create all time-dependent properties in Civil NX

print("All time-dependent properties and links created successfully!")
# You can also create them all at once using Material.createAll() if materials exist
# Material.createAll() # This creates materials, creep/shrinkage, compressive strength, and links
