Simple IBM Solver

Overview

This library numerically simulates the motion of rigid particles in two- and three-dimensional Cartesian domains using the finite-difference and immersed boundary methods.

Dependency

This solver is built on top of SimpleNSSolver. Please check its repository for dependency details.

Quick Start

1. Set up your workspace

   mkdir -p /path/to/your/directory
   cd /path/to/your/directory

2. Clone the repository

   git clone --recurse-submodules https://github.com/NaokiHori/SimpleIBMSolver
   cd SimpleIBMSolver

3. Set the initial condition

   Python 3 is used to conveniently initialize the flow fields. Alternatively, NPY files can be provided in a different manner under initial_condition/output/.

   cd initial_condition
   make output
   bash exec.sh
   cd ..

4. Build the solver

   make output
   make all

5. Run the simulation

   bash exec.sh

Note

The immersed boundary method and the collision model are based on this publication with some modifications.
