Function Documentation

function [ INC , fluxes ] = fv_space_operator	(		model,
			model_data,
			U,
			NU_ind,
			weights
	)

fv_space_operator(model,model_data,U,NU_ind,grid,weights)

function applying an FV-space-discretization operator starting from old values U corresponding to the geometry given in model_data.grid producing a new vector of elementwise scalars NU but only on for the subelements with numbers given in NU_ind. If NU_ind is empty, all new values NU are determined, i.e. length(NU) = length(U) = grid.nelements

By this, the operator evaluation can be performed in a localized way, i.e. used for empirical interpolation in e.g. rb_nonlin_evol_simulation

usual timestepping can be performed afterwards by (NU = Id - deltat * INC).

Parameters

model	model
model_data	model data
U	U
NU_ind	NU ind
weights	weights

Return values

INC	INC
fluxes	fluxes
