This repository contains a 2D fluid simulation in C++ developed for the Major project Milestone 1. If you have any issues building or running please don't hesitate to reach out: . All code in this project is POSIX-compliant C++11.
Building and incremental builds is all set up with a Makefile. To build run:
module load cuda
module load gnu
make
Note: simulation parameters are hardcoded at build-time, these may all be found and modified in src/main.cu
There are two components to run. The first is the particle simulation itself which can be run with ./particle-sim.
Once particle-sim has run, some out files will be generated in your current working directory, these will be used by the second component - the visualisation scripts.
Note: if you run this on the Getafix console node (which you shouldn't) file logging doesn't work (likely due to some kind of disk io rate limit)
Note: The directory which this log file is written to is configurable on src/output.cpp:6. If you do change this make sure you update the scripts in debug/ to reflect this new path
To run the visualisation scripts:
* Generate a video (mp4) of the simulation: python3 debug/visualise.py
* Generate a plot of the centre of gravity throughout the sim: python3 debug/cg.py
Note: the visualisation tools have the following dependencies: python, numpy, matplotlib, and ffmpeg
