Abstract
Motion of a continua such as fluids or solids is computed with finite number of particles in particle method. The phenomena with complex motion of surfaces or boundaries are easily simulated. We are developing a multiphysics simulator using a particle method for micro biochemical systems where complex phenomena with surfaces and boundaries take place. In this article, we consider to improve the accuracy of the particle methods as the first step to the multiphysics simulator and develop a new particle method from a discretization of the Lagrangian which describes incompressible fluid flow. Some calculations indicate a superior conservation property of the method.
