Improved accuracy of the algorithm for automatically generating the analytical model

The algorithm for automatically generating the analytical model has been improved in the following ways:

• The process used to assign the properties of the walls and floor slabs in the physical model to the surfaces generated in the analytical model has been optimised.
• A problem in the process of detecting openings in the physical model (doors, windows, skylights, etc.) that could generate openings in analytical surfaces where this was not necessary has been corrected.
• An error caused by the generation of edges with a length of zero after the analysis of the surfaces of the analytical model has been corrected.
