source terms are handled in a manner similar to that in the immersed boundary (IB) method of
Peskin (2002). The numerical scheme implements a second-order pressure-free projection method
due to Kim and Moin (1985) and completely obviates the difficulties that may be faced in prescribing
Neumann pressure boundary conditions. The proposed SPH method is first tested on the
planar start-up Poiseuille problem and a detailed error analysis is performed. For this problem,
the results are similar whether the SPH particles are free to move or fixed on a regular grid. Our
hybrid SPH-IB method is then used to calculate the dynamics of a stretched immersed elastic
membrane and the advantages in this case of fixing the SPH particles, rather than allowing them
to move with the fluid, are discussed.},
