We consider a second order elliptic boundary value problem in the variational form: find uH01(Ω), for a given polygonal (polyhedral) domain \(\varOmega \subset \mathbb{R}^{d},\,d = 2,3\) and a source term fL2(Ω), such that
$$\displaystyle{ \underbrace{\mathop{\int _{\varOmega }\nabla u^{{\ast}}(x) \cdot \nabla v(x)\,dx}}\limits _{\equiv a(u^{{\ast}},v)} =\underbrace{\mathop{ \int _{\varOmega }f(x)v(x)\,dx}}\limits _{\equiv (f,v)},\quad \text{for all }v \in H_{0}^{1}(\varOmega ). }$$
The Bank–Holst parallel adaptive meshing paradigm [1–3] is utilised to solve (1) in a combination of domain decomposition and adaptivity.
