Lagrangian Phase ModelIntegration of Motion Equation• Motion equation for a particle is an Ordinary Differential Equation (ODE)• During integration, particle traverses a number of cells <strong>and</strong> continuous phaseproperties are updated based on its position• For accurate integration, motion equation is formulated as an ODE <strong>and</strong> solverusing an ODE solverParticle Tracking• Cell-to-face-to-cell tracking: no inverted Jacobians, no lost particles• If more accurate integration is necessary, sub-cycling is usedIntegration stencilUCyprus Advanced <strong>HPC</strong> Workshop Winter 2012.
