CFD2021-G4-Projects

This repository dedicates to the team projects related to the computational fluid dynamics course by Prof. Ren, 2021 spring, at SAS, THU.
Efforts are contributed by a joined 4-member group.
For practice and performance, we attempt to use the programming language in these projects.

Configuration

The project is mainly written in Julia, albeit may also marginally used. As CFD is a mature community we utilized various robust tools built by the community, which require user/contributors to do some preparation before setting the project up.

Prerequisites

To use or contribute to the project, these tools should be previously installed:

Setup

Clone the repository with :

git clone git@github.com:tsinghua-TEEP/CFD2021-G4-Projects.git

Instantiate the dependencies.
- (to be implemented) In the root directory of the repository, run:
```
python ./setup.py
```
- For now, you need to instantiate the dependencies yourself.
  - Julia: type julia in the OS shell to enter the Julia REPL, then type ] to enter the Pkg interface; from there:
```
(@v1.6) pkg> activate .
(CFD2021Projects) pkg> instantiate
```
  in case you need to update the dependencies after that, do
```
(CFD2021Projects) pkg> update; precompile
```
  - Conda: in the repo root, from the OS shell execute
```
conda env create --prefix ./.conda/env/CFD2021-G4-Projects --file ./conda-environment.yml
```
  - Git submodules: some of the dependencies are git submodules. In the repo, from the OS shell execute
```
git submodule update --init --recursive
```

Projects are listed as below:

Project 1

Analytical and elliptic grid generation for geometrical and general setups.

TODOs:

General purpose solver for the inverted Poisson equation. (see gauss-seidel.jl from CFD-Julia)
Processing general NACA airfoils (formula generation, discretization, splining, etc.)
Port the output to standard format.
