The adjustment methodology consists in an iterative process where some parameters are modified, thesimulation is run, results are checked and some parameters are modified again until results are good enough.The differences between simulation results and experimental data will show very different behavioursdepending on the case studied. Also during the process of adjustment these differences will evolve in a differentway. For this reason, is not possible to give standard rules for the adjustment procedure but only some generaladvises based on the work followed in this case.
