A fast immersed boundary method using a nullspace approach and multi-domain far-field boundary conditions

We report on the continued development of a projection approach for implementing the immersed boundary method for incompressible flows in two and three dimensions. Boundary forces and pressure are regarded as Lagrange multipliers that enable the no-slip and divergence-free constraints to be implicit...
