Research direction

No files or tests are named. Start by locating the existing structured-grid VTK writer, then review the example code from @FTW12345 and Flopy's exporters. Done means supporting unstructured DISV grids and exporting complete simulations, including grid data and a .pvd model structure readable by Paraview or PyVista.

Description

enhancement

Part of the wishlist on our roadmap, we could do with some exporters to VTK to easily view things in 3D viewers like Paraview or PyVista. We already have a function to write structured grids to VTK for PyVista, but lack this for unstructured grids (DISV). This is low-hanging fruit.

Furthermore, we'd like to be able to export a complete simulation to VTK. Griddata will be exported to VTK files, and the model structure can be stored in a .pvd file for which both Paraview and PyVista have readers.

@FTW12345, mentioned he had some example code which can be our starting point. Furthermore I know Flopy also has some exporters we could take inspiration from.
