Crushing of a block made of steel by a cylindrical punch

What is written in the file tutorial1.py ?

• An input file of Metafor is a python module which contains a function getMetafor(p)
• This function is supposed to create a Metafor object
• The Metafor object is the main object containing everything about a FE simulation (geometry, mesh, boundary conditions, materials, integration scheme, etc.)

Main idea: The input file creates a complete data structure and returns it to the FE code

Data structure of a model

First lines – header of the file

from wrap import *
import math

• coding:latin1 is required for French accentuated characters
• miscellaneous comments
• import the C++/python interface of the program (remember the wrap folder in the installation tree)
• import the math module of python for later use

metafor = Metafor()
domain = metafor.getDomain()

def getMetafor(p={}): return metafor

Creation of an instance of the Metafor class (for now it is almost empty) We name it metafor

Any Metafor object contains a Domain object. We retreive the Domain and we name it domain

We define the getMetafor() function (same for all models)
