5.2.1 Top-down analysis

 
Figure 5.1: The domain under consideration 

The domain of interest is shown in figure 5.1. The analysis of the geometry and the presence of several materials leads us to define four principal parts:

i
the shield (part 4.4 of the figure): its quadrilateral form urges us to use the QUACOO mesh generator, i.e. the algebraic method producing elements of a quadrilateral nature constructed from the input data consisting of the contour of the part considered; the data consists of the 4 sides (from a topological point of view);
ii
the air zone (part 4.3 of the figure): it corresponds to the quadrilateral pierced by a square; this implies that the boundary of this part has 2 components; consequently, we will use the TRIHER mesh generator, i.e. the Voronoi method producing triangular elements constructed from the input data consisting of the contour of this part; the data consists of the union of the constituent lines;
iii
the semiconductor (part 4.2 of the figure): due to its shape, we use, again, mesh generator TRIHER (Voronoi method) which requires the contour of this part as input data (i.e the union of the constituent lines);
iv
the half-cooling circuit (part 4.1 of the figure): due to its shape, we will again use mesh generator TRIHER.

The "gluing together" of the meshes of 4.1 and 4.2 (module RECOLC) will result in the mesh of the corresponding half-square. By symmetry (module
[4] MODNOP), we will obtain the mesh of the symmetric part of the half-square; by "gluing" it to the preceding mesh (module RECOLC), the complete mesh of the cooling circuit and its conductor will be constructed.

It remains to "glue" (module RECOLC) this mesh to that of the air zone and then "glue" this result to the mesh of the shield; finally, the end-result will be stored on file (module SAUVER).

The set of modules necessary is therefore the following:

In terms of keywords of APNOPO, we have:

In terms of data, we have successively:

In terms of keywords of APNOPO we therefore need, in addition:
