WebJun 27, 2011 · A new cut-cell method to simulate the interaction of a viscous fluid with rigid boundaries and aims at suppressing spurious force oscillations which are typically encountered in sharp interface Cartesian methods applied to moving boundary problems and may deteriorate the accuracy of the fluid-structure momentum exchange. The cut-cell approach is used for dealing with material boundaries embedded within a structured (usually Cartesian) computational grid. Since it does not require any adjustment of the underlying logically rectangular mesh, it avoids the mesh-generation issues associated with other methods for dealing with complicated solid boundaries, such as ... excruciating si joint pain and hip pain
