This data distribution generates a set of nodes belonging to
a non-empty intersection of subdomains :
![$ x_{C_{i,j}}\in \overline{\Omega} \makebox[0pt]{}_{h,i} \cap \overline{\Omega} \makebox[0pt]{}_{h,j}\enspace$](img479.gif)
.
This distribution may have advantages if upwind techniques are used in FEM.
