Hi, everyone!

I made **ElasticWave2D.jl** — GPU-accelerated 2D elastic wave simulation in Julia.

![wavefield](https://global.discourse-cdn.com/julialang/original/3X/5/1/5124835211e104f2ad0366f5eafdcaa8a42714c3.gif)

I wanted to explore Julia’s potential for seismic simulation — easy install, GPU support, and readable code.

**Features:**

- CUDA acceleration (also multi-threaded CPU with `-t auto`)
- Staggered grid FD, HABC boundaries
- Vacuum formulation for topography & cavities
- Video recording, multiple output formats

**Example result** (tunnel detection):

**Install:**

```julia
using Pkg
Pkg.add(url="https://github.com/Wuheng10086/ElasticWave2D.jl")

```
