Material

The module provides functionality to create, manage, and synchronize materials in the model.

Note.

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

from midas_civil import *
MAPI_KEY('eyJ1ciI6InN1bWl0QG1pZGFzaXQuY29tIiwicGciO252k81571d')

---

Class Attributes

Material.mats -> List of all material instances.
Material.ids -> List of all material IDs.

# Example material data

mat1 = Material.CONC("M30 Grade","IS(RC)","M30",1)
mat2 = Material.STEEL("S450 Steel", "EN05(S)", "S450", 2)
mat3 = Material.USER("Timber", E=12000, pois=0.4, den=6, mass=6, therm=5e-6, id=3)

Material.create()

Methods

---

json

Returns a JSON representation of all Materials defined in python.

print(Material.json())
# Output:
# {'Assign': {1: {'TYPE': 'CONC', 'NAME': 'C30', 'DAMP_RAT': 0.05, ...}}}

create

Sends the current materials, creep shrinkage, compressive strength and time-dependent material links to Civil NX using a PUT request.

Material.create()

get

Fetches materials from Civil NX and returns the JSON representation.

print(Material.get())

sync

Retrieves Material data from Civil NX and rebuilds the internal material list.

Material.sync()

delete

Deletes all material data from both Python and Civil NX.

Material.delete()

# Create user-defined concrete material

# Create steel materials from database
steel1 = Material.STEEL("S450 Steel", "EN05(S)", "S450", 4)
steel2 = Material.STEEL("Fe540 Steel", "IS(S)", "Fe540", 5)

# Create user-defined steel material
steel_user = Material.STEEL.User("Custom Steel", E=200000, pois=0.3, den=78.5, mass=7.85, therm=1.2e-5, id=6)

# Create generic user material
user_mat = Material.USER("Timber", E=12000, pois=0.4, den=6, mass=6, therm=5e-6, id=7)

# Create all materials in Civil NX
Material.create()

print("All materials created successfully!")
