GSPH implementations in the literature discretize the momentum equation in more than one way. This selects between:

• ChaWhitworth: the symmetric SPH form (nabla_W/rho^2/Omega) with p* substituted for pressure, following Cha & Whitworth (2003). This is shamrock's default.
• InutsukaV2: the effective volume/face form (V2_ij * grad_W_ij) following Inutsuka (2002), reconstructed here with linear (1st order) face interpolation.
