We study a fixed-feature solver, referred to as Spectral-ELM, in which Chebyshev--Gauss--Lobatto (CGL) differentiation matrices are applied to the nodal values of an extreme learning machine (ELM) trial function. Curved domains are treated using a mapped multi-patch formulation. Each curved quadrila
