Interactive geometry software for Euclidean and non-Euclidean spaces
GeomSpace is interactive geometry software for different geometric spaces. You can build your own universe of any dimension and with any geometry. You can choose Euclidean, elliptic, hyperbolic, Galilean, Minkowskii, de Sitter among other spaces.
WDSolve is a black box solver for nonlinear hyperbolic partial differential equations. WDSolve is based on the
Wave Digital method, leading to explicit finite difference schemes with superior stability properties.
