Simple IBM Solver

_ _

Overview

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

Dependency

This is built on top of SimpleNSSolver. Please visit it and check the dependency there.

Quick start

1. Prepare workplace

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

2. Get source

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

3. Set initial condition

   Here Python3 is used to initialise the flow fields conveniently. One can give NPY files in different way under initial_condition/output/.

   cd initial_condition
   make output
   bash exec.sh
   cd ..

4. Build solver

   make output
   make all

5. Run

bash exec.sh

Note

The immersed boundary method and the collision model is based on a publication with some modifications.
