Goal-based angular adaptivity applied to the spherical harmonics discretisation of the neutral particle transport equation

•A variable order spherical harmonics scheme is presented.•An adaptive process is proposed to automatically refine the angular resolution.•A regular error estimator and a goal-based error estimator are presented.•The adaptive methods are applied to fixed source and eigenvalue problems.•Adaptive meth...
