Function Documentation

function reduced_data = dom_dec_gen_reduced_data	(		model,
			detailed_data
	)

all required offline data for the rb-simulation is computed. there are two ingredients for the error estimator - the jump across \(\Gamma\) and the residuum.

the computation of residuum-components needs Q_f+N1*Q_A1+N2*Q_A2 detailed simulations. the number of iterations is very high there, because the accuracy of the error estimator is good then. therefore very expensive computations.

Parameters

model	model
detailed_data	detailed data

Return values

reduced_data

reduced data
