Function plotting the solution of an equation on a hypergraph in vtu format.

Creates a file according to set plotting options in plot_options. This file contains the solution of the PDE defined in plotOpt having the representation lambda in terms of its skeleta degrees of freedom (related to skeletal variable lambda).

Template Parameters

HyperGraphT	Template parameter describing the precise class of the `HDGHyperGraph`, i.e., it contains an `HDGHyperGraph` with chosen template parameters describing its topology, geometry, etc.
LocalSolverT	Template parameter describing the precise class of the local solver, i.e., it contains an local solver for a specific equation living on the hypergraph.
LargeVecT	The typename of the large vector.
floatT	The floating point type in wihch time is given of dof values.

Parameters

hyper_graph	The hypergraph.
local_solver	The local solver.
lambda	Large vector containing the skeletal degrees of freedom encoding the representation of the unique solution.
plot_options	PlotOptions object containing plotting options.
time	The time stamp.
