Protoplanetary disc simulation must be done first, with high precision, and second, with high speed. Some strategies to reach
these goals are presented in the paper. They include: the reduction of the 3D protoplanetary disc model to quasi-3D, the use
of fundamental Poisson equation solution, the simulation in the natural (cylindrical) coordinate system and computation domain
decomposition. The
... [Show full abstract] domain decomposition strategy is shown to reach the simulation goals the best.
