A strongly coupled algorithm is presented for the incompressible fluid–rigid body interaction using moving immersed boundary method. The pressure and force are treated as Lagrange multipliers to enforce incompressibility no-slip wall constraints. To compute two unknowns from velocity field, we adopt fractional step successively apply Poisson equation a derived force, respectively. As both coeff...

Abstract Switching options can be deployed in various complex switching problems such as tolling agreements and the offshoring-backshoring problem. Closed form solutions to valuing are not only hard, but also computationally intensive when solving numerically. We develop a new computational method value based on moving boundary method. show how free problem arising from converted into sequence ...
