dolfinx::io::VTKFile Class Reference

Output of meshes and functions in VTK/ParaView format. Isoparametric meshes of arbitrary degree are supported. For finite element functions, cell-based (DG0) and Lagrange (point-based) functions can be saved. For vertex-based functions the output must be isoparametic, i.e. the geometry and the finite element functions must be defined using the same basis. More...

Detailed Description

Output of meshes and functions in VTK/ParaView format. Isoparametric meshes of arbitrary degree are supported. For finite element functions, cell-based (DG0) and Lagrange (point-based) functions can be saved. For vertex-based functions the output must be isoparametic, i.e. the geometry and the finite element functions must be defined using the same basis.

This format if It is not suitable to checkpointing as it may decimate some data.
