This repository contains the source code and data for a paper submission. The code performs CFD simulations of flow past a cylinder or sphere using the Basilisk framework.

Main Code

The main simulation code is located in the /cylinder directory. It is built upon the Basilisk CFD solver.

Directory Structure

• /cylinder: Contains the main simulation source code.

  • cylinder.c: The main program for the fluid simulation.
  • centered.h: Incompressible Navier-Stokes solver implementation.
  • Makefile: Used to build the simulation executable.
  • README.md: Provides instructions for installing dependencies and building the code.
  • /deploy: Contains scripts and pre-processed files for running simulations on different systems.

• /dump: Contains utilities for handling simulation data dumps.

  • dump2xdmf.c: Converts simulation dump files to XDMF format for visualization.
  • stl2dump.c: Generates a Basilisk dump file from an STL geometry file to initialize a simulation domain.

• /geom: Contains various scripts for geometry processing.

• /stl: Contains utilities for creating and manipulating STL files (e.g., cylinder.py to generate a cylinder geometry).

How to Run

1. Install Dependencies: The main dependency is the Basilisk CFD framework. Follow the instructions in /cylinder/README.md to install it.

2. Build: Navigate to the /cylinder directory and use the Makefile to build the executable:

   cd cylinder
   make

3. Run Simulation: The scripts in the /cylinder/deploy directory provide examples of how to run the simulations with different parameters. For example, you can use run.sh to start a simulation from a pre-generated dump file.

   cd cylinder/deploy
   ./run.sh
