INTRODUCTION

In the context of developing energy simulation applications for buildings, there is a need for more sophisticated emulation tools.Exa-MA(Methods and algorithms for Exascale) project [1] part of the Numpex project [2] is a French initiative to adress those issues by developing exascale application for simulation. CEMOSIS [3] in collaboration with CoE Hidalgo2 [4] initiative is contributing to the project by porting the Ktirio Urban building [5] application which focuses to energy simulation in urban places to the exascale power.

My internship is focussed on developing a tool for geometric reconstruction of building at a level of details 2 (LOD 2). This is a classification of the level of details and informations avaible in a 3D mesh modele in IFC (industry foundation class) The goal is to generate Volumetric meshes with some constraint of conformidity and watertightness which are necessary for simulation such as FEM (Finite Element Method).

To achieve this we will utilize new algorithms name Kinetic, developed by Inria Titane Team [6]. We will have to follow the following steps in order to succeed:

  • Checking the validity of the mesh provided by IFC files, some correction may be necessary.

  • Setting an automatic workflow for mesh Generation using Kinetic.

  • Setting some quality test.

  • Setting the correspondance between the IFC element and the mesh element.
