Assessing the respective capabilities of LP and CFD codes [149, 154].

Parameter	LP codes	CFD codes
Computational time	Relatively fast running	Long computational time
Number of nodes	Adequate (≈100 control volumes)	Fine (≈105 cells, cell size ≈10^-11 m^3)
Input parameter	Modest	Local data input required at each cell
Validation	Large validation base available	Limited
Parametric study	Feasible due to fast computing	Limited due to long computational time
Predicting flow paths	Adequate for sufficient nodes	Well predicted
