1. MaterialLibraryModel

A MaterialLibraryModel is a database containing a list of MaterialModel.

Name	Return	Description
GetMaterialByDescription()	MaterialModel	Access to a materialModel by its description (param1)
MaterialDescriptionExists()	bool	Return True if a material exists with this description (param1)
SetRefTemperature()	-	Set the reference temperature (param1) for all materials [°C in metric units]
AddMaterial()	MaterialModel	Add an empty materialModel to the library (without description)
DeleteMaterial()	-	Delete the materialModel (param1) from the library
Save()	-	Save the library

1.1 MaterialModel

A MaterialModel represents the definition of a material.

Name	Return	Description
Description		The description of the material
MaterialType		The type of material
MaxTemperature		Temperature max [°C in metric units]
RO		Density [kg/m³ in metric units]
SG		Poisson’s ratio
Properties		List of MaterialProperties
Properties.Count	int	Number of MaterialProperties
Properties.[i]	MaterialProperties	ith MaterialProperties
AddProperties()	MaterialProperties	Add a new line of properties for a temperature
Deleteproperties()	-	Delete a MaterialProperties (param1)

1.2 MaterialType

To access the MaterialType property of a MaterialModel, you need to import the object from Cwantic.MetaPiping.Core :

# Python script   
from Cwantic.MetaPiping.Core import MaterialType

Values :
MaterialType.CarbonSteel
MaterialType.LowAlloySteel
MaterialType.MartensiticSteel
MaterialType.AusteniticSteel
MaterialType.NickelChromeSteel
MaterialType.NickelCopperSteel
MaterialType.Other
MaterialType.Composite
MaterialType.HDPE

Example :

# Python script   
from Cwantic.MetaPiping.Core import MaterialType
...
if mat.MaterialType == MaterialType.CarbonSteel:
    ...

1.4 Example

Imagine user wants to get the first temperature of a specific MaterialModel (study.Inputs[1]) from a specific library (study.Inputs[0]). Result as a text in Outputs[0].

# Python script   
libname = study.Inputs[0]
matname = study.Inputs[1]

lib = study.getMaterialLibraryModel(libname)
if lib != None:
    mat = lib.GetMaterialByDescription(matname)
    if mat != None:
        study.Outputs[0] = str(mat.Properties[0].TE)
    else:
        study.Outputs[0] = "Material not found !"
else:
    study.Outputs[0] = "Library not found !"
