Mesh to grid functionality?

[rlawglacio]

Hi there,

I'm working on an external function that is interoperable with a number of ice sheet model, so meshio is fantastic for getting a variety of mesh formats into Python.

What I can't find functionality for however, is converting from a mesh to a grid. As the external function operates on grids I need to do this to ensure compatibility. I've done quit a bit of searching online and it seems like the vtk python module will do this, however that has a lot of library dependencies which I'm keen to avoid.

So I'm wondering (1) is this functionality actually already in meshio or am I just missing it? and If not (2), shall I write a meshio function to do this?

Cheers,
Rob
