Large deformation simulations of geomaterials using moving particle semi-implicit method

Simulation of red blood cell motion in microvessels using modified moving particle semi-implicit method

Moving particle semi-implicit; Red blood cell; Micro-capillary. Abstract Red Blood Cells (RBCs) are the main cells in human blood, with a main role in the mechanical properties of blood as a fluid. Several methods have been improved to simulate the mechanical behavior of RBC in micro-capillaries. Since, in microscopic scales, using discrete models is more preferred than continuum methods, the M...

Moving Particle Semi-implicit Method: Fully Lagrangian Analysis of Incompressible Flows

Moving Particle Semi-implicit (MPS) method is based on fully Lagrangian description. Particle interaction models are prepared for differential operators, such as gradient, divergence and Laplacien. Governing equations are transformed to interactions among moving particles. Grids are not necessary. Large deformation of interfaces can be analyzed without grid tangling. Numerical diffusion does no...

Real-time Bleeding Simulation Based on Moving Particle Semi-implicit Method

Computer graphics and virtual reality technologies have enables us to develop several medical systems such as preoperative planning, intra-operative navigation and surgical simulation systems. The training for each part of human bodies is available, which parts are head, eye, liver, bone and so on; however, real-time simulation of blood vessel deformation or bleeding is not available with the p...

An efficient semi-implicit compressible solver for large-eddy simulations

In most combustion devices, the Mach number is small, and the most efficient computational approach is the solving of the low-Mach number formulation of the Navier-Stokes equations. In this approach, the acoustic waves propagate at an infinite speed. Nevertheless, when the acoustic speed plays an important role, as in the formation of instabilities, the compressible Navier-Stokes equations must...
