HyENA - Hyperbolic and Elliptic Numerical Analysis. HyENA is a C++ library for the numerical solution of partial differential equations using the boundary element method (BEM). The following features are provided: Library for 3D domains; Continuous and discontinuous shape functions; Galerkin and collocation methods for spatial discretization; Convolution Quadrature Method (CQM) for temporal discretization; Fundamental solutions for different elliptic and hyperbolic problems; Support for fast boundary element methods based on H-matrices and ACA
