  • DIRECT SIMULATION MONTE CARLO FOR DENSE HARD SPHERES 
    Chao, Liu; Kwak, Sang Kyu; Ansumali, Santosh (World Scientific Publ Co Pte Ltd, 2014)
    We propose a modified direct simulation Monte Carlo (DSMC) method, which extends the validity of DSMC from rarefied to dense system of hard spheres (HSs). To assess this adapted method, transport properties of hard-sphere ...
  • Diffused bounce-back condition and refill algorithm for the lattice Boltzmann method 
    Krithivasan, Siddharth; Wahal, Siddhant; Ansumali, Santosh (American Physical Society, 2014)
    A solid-fluid boundary condition for the lattice Boltzmann (LB) method, which retains the simplicity of the bounce-back method and leads to positive definite populations similar to the diffusive boundary condition, is ...
  • Delayed Difference Scheme for Large Scale Scientific Simulations 
    Mudigere, Dheevatsa; Sherlekar, Sunil D.; Ansumali, Santosh (American Physical Society, 2014)
    We argue that the current heterogeneous computing environment mimics a complex nonlinear system which needs to borrow the concept of time-scale separation and the delayed difference approach from statistical mechanics and ...
  • Crystallographic Lattice Boltzmann Method 
    Namburi, Manjusha; Krithivasan, Siddharth; Ansumali, Santosh (Nature Publishing Group, 2016)
    Current approaches to Direct Numerical Simulation (DNS) are computationally quite expensive for most realistic scientific and engineering applications of Fluid Dynamics such as automobiles or atmospheric flows. The Lattice ...
  • Fokker-Planck model of hydrodynamics 
    Singh, S. K.; Ansumali, Santosh (American Physical Society, 2015)
    We present a phenomenological description of the hydrodynamics in terms of the Fokker-Planck (FP) equation for one-particle distribution function. Similar to the Boltzmann equation or the Bhatnager-Gross-Krook (BGK) model, ...
  • On vectorization for lattice based simulations 
    Shet, A. G.; Kaul, B.; Siddharth, K.; Sorathiya, S. H.; Deshpande, A. M.; Sherlekar, S. D.; Santosh Ansumali (World Scientific, 2015-04-16)
