There is direct support for saving and visualizing data using the GraPE library, for generating VTK output, and Matlab data files.
- GraPE: Data can be either visualized directly during a computation using the DataWriter class. The same format is also used for checkpointing. It can be visualized through the datadisp program which can also read a time series of data.
- VTK: Discrete functions can be written to a file either as element data (piecewise constant function) or as vertex data (piecewise linear function) on a flat grid. Again, the DataWriter is used. Note that the resulting files cannot be used for checkpointing since the grid hierarchy is lost.
