Issue/feature addressed
VTK output was manually written, which is slow and results in large uncompressed files
Proposed solution
Adds a VTK output option using the VTK library
Implementation
Renamed old output to OutputVtkLegacy, implemented a new OutputVtk which makes use of the VTK library to achieve a number of things such as custom compression levels 1-9, high order VTK output, multiblock output, cached mesh when using filters.
Supports:
- Old linear: Whatever it was before
- New linear: 1D, 2D, 3D, 3DH1D (cached mesh when filter FieldConvert)
- High order: 1D, 2D, 3D except pyramids (cached mesh when filter FieldConvert)
- Multi-block: 1D, 2D, 3D
