fem_2d_mesh_plot

A Mesh visualization tool for the fem_2d library.

fem_2d allows mesh files to be exported in a json format compatible with this library:

use fem_2d::prelude::*;

// load a raw mesh file (this is an alternate format, not compatible with this library)
let mut mesh = mesh::from_file("./input_files/some_mesh.json").unwrap();

// execute some refinements
mesh.set_global_expansion_orders([3, 4]).unwrap();
mesh.h_refine_elems(vec![0, 3, 4, 6], HRef::T).unwrap();

// export the mesh file 
mesh.export_to_json("./output_files/refined_mesh.json").unwrap();

This tool allows mesh files to be visualized in 3D, and exported as images

Installation

1. Install Node.js if you haven't already
2. Download or clone this repository to a directory of your choice
3. Navigate to that directory in a terminal and run the command npm install

Operation

1. Using the same terminal pointed at the directory containing this repo, run node server.js in the terminal
2. Navigate to localhost:3000 in your browser
