Material

1. Material

Material is the base class for all materials. In MKS units !

1.1 Properties

Name Type Description
Name String Material name
Type MaterialType Type of material
Target MaterialTarget Target, see below
RefTemperature Float Reference temperature
ThermalExpansionOption Int  
Density Float Density
Poisson Float Poisson coefficient
MaxTemperature Float Max temperature
Description String Description

MaterialTarget can be:

Piping
Structure
Bolting
Welding

# Python script
from Cwantic.MetaPiping.Core import MaterialTarget

target = MaterialTarget.Piping

2. RegularMaterial

RegularMaterial inherits from Material. Every RegularMaterial object has the properties of Material.

RegularMaterial represents regular materials which properties are independent of time but dependant of temperature.

2.1 Properties

Too complex. Use MaterialLibraryModel object to load a *.materials from database.

# Python script
from Cwantic.MetaPiping.Core import MaterialLibraryModel

library = MaterialLibraryModel("");
library.LoadFromFile(libraryFilename);
materialModel = library.GetMaterialByDenomination(materialName)
material = materialModel.GetMaterial(library.Units) # In MKS units
...

MaterialModel

Class of material in USER units !

# Python script
from Cwantic.MetaPiping.Core import MaterialModel

materialModel = MaterialModel()
...
