2DMeshSandbox

Physical modeling of circular membrane using 2D waveguides.

Building

To clone the repository, run the following command:

git clone https://github.com/Segfault1602/2DMeshSandbox.git --recurse-submodules

If you forgot to clone the submodules, you can run the following command to fetch them:

git submodule update --init --recursive

This project uses CMake to generate the build files. To build the project, run the following commands:

cmake -GNinja -Bbuild
cmake --build build

This project was tested and compiled on MacOS 15.1 using AppleClang 16.0.0 but should work on other platforms as well.
