Hi, I want to solve a reaction-diffusion equation on a 2D polygonal mesh, where each cell has a different parameter value for the reaction-diffusion equation. I have the mesh in the VTK format. Now I wonder whether I should simply write a script to convert the VTK data into a JuAFEM grid or whether there exists some IO functionality for that in the Julia package universe. Thanks for any hints.

One option is to make use of [meshio](https://github.com/nschloe/meshio) if you don’t want to implement it yourself.  
It can be easily called from julia via PyCall.
