modelHomogeneousNLayersWall
Extends from BuildSysPro.BaseClasses.HeatTransfer.Components.Wall (Model of wall composed of one or more materials described from outside to inside).
Information
Model of 1-D thermal conduction in an N layers material
Uses the Wall component, which derives from the Material and MaterialLayer components.
Hypothesis and equations
none
Bibliography
none
Instructions for use
none
Known limits / Use precautions
The T variable gives the temperature in the middle of each node (m equidistants meshes on the given ep thickness).

Revisions
Hassan Bouia 06/2012 : correction du bug qui empêchait le fonctionnement du modèle lorsqu'on ne saisissait qu'un seul matériau avec une seule couche.
Hassan Bouia 04/2014 : changement de la modélisation de la paroi - elle est désormais représentée par une Paroi composée de Materiau(x), eux-mêmes composés de CoucheDeMateriau.
