Solving Integral Equations on Piecewise Smooth Boundaries Using the RCIP Method: A Tutorial

Figure 19

Meshes of type a, type b, and type c on the boundary subset Γ^⋆_𝑖 for 𝑖=3 and 𝑛_sub=3. The type a mesh has 4+2𝑖 panels. The type b mesh has six panels. The type c mesh has four panels. The type a mesh is the restriction of the fine mesh to Γ^⋆_𝑖. For 𝑖=𝑛_sub, the type c mesh is the restriction of the coarse mesh to Γ^⋆. The type a mesh and the type b mesh coincide for 𝑖=1.
