Add a grid function (represented by container) that lives on the cells of the grid to the visualization.
The container has to have random access via operator[] (e.g. std::vector). The value of the grid function for an arbitrary element will be accessed by calling operator[] with the index (corresponding to the index from the MGMC mapper on the grid view) of the element. For vector valued data all components for an element are assumed to be consecutive.
v | The container with the values of the grid function for each cell. |
name | A name to identify the grid function. |
ncomps | Number of components (default is 1). |

p | std::shared_ptr to the function to visualize |
|
inline |
Add a function by sampling it on the element centers.
f | The function to be written to the file |
The object f can be one of several things. Depending on what it is exactly, its object life-time is influenced in different ways:
The previous paragraph actually refers to parts of the dune-functions interface, and you may want to read up on that if you want to write functions to VTK.

path | Directory where to put the parallel collection (.pvtu/.pvtp) file. If it is relative, it is taken realtive to the current directory. |
extendpath | Directory where to put the piece file (.vtu/.vtp) of this process. If it is relative, it is taken relative to the directory denoted by path. |

write output (interface might change later)
"pwrite" means "path write" (i.e. write somewhere else than the current directory). The "p" does not mean this method has a monopoly on parallel writing, the regular write(const std::string &, VTK::OutputType) method can do that just fine.

write output (interface might change later)
This method can be used in parallel as well as in serial programs. For serial runs (commSize=1) it chooses other names without the "s####-p####-" prefix for the .vtu/.vtp files and omits writing of the .pvtu/pvtp file however. For parallel runs (commSize > 1) it is the same as a call to pwrite() with name and path constructed from a given filename possibly containing a path, and extendpath="".
