Abstract

Interactive blood flow simulation has applications in the understanding of complex fluids,training medical professionals, diagnostics, and surgical procedure planning. Bidirectional in situ visualization and analysis are much needed to streamline the analysis of large-scale patient-specific blood flow simulations. The in situ component ensures the live visualization of the simulation results while the simulation is running, and the bidirectional component allows for real-time control and configuration of the simulation parameters (i.e., setting and retrieving the simulation parameters and data based on need). In this project, a highly accurate multiphysics simulation was instrumented to work with an existing bidirectional in situ framework. A visualization and analysis tool was developed for interactive blood flow simulations. The highly accurate multiphysics simulation is achieved by coupling the fluid and solid solvers Palabos and LAMMPS using the immersed boundary method (IBM). The fluid solver uses the lattice Boltzmann method (LBM). Blood cells are modeled using coarse-grained molecular dynamics and are immersed in fluid. Different types of cells can be inserted in the simulation to model diseases such as inflammation, cancer, etc. Showcases were created to demonstrate the capabilities of the tool.
