Detailed Description

Generic SPH solver, evaluating equations for each particle separately.

Contrary to SymmetricSolver, this solver computes the derivatives for each particle separately, meaning each particle pair is evaluated twice (or not at all, of course). This leads to generally slower evaluation, as we have to compute twice as much interactions. However, the solver is more versatile and can solve equations with asymmetric derivatives. This allows to use helper terms (like strain rate correction tensor) that require two passes over the particle neighbours; the derivative is completed after the neighbours are summed up, as the list of neighbours contains ALL of the neighbouring particles (as opposed to SymmetricSolver, where the list of neighbours only contains the particles with lower smoothing length).

Another benefit is lower memory overhead (all threads can write into the same buffers) and generally higher CPU usage.
