GWP specify own limit-values for AQUACHEM

with the additional Tool: GWP up to 2 different limit-lists could be specified. AQUACHEM will control all input values by your individual limit values. (ex. in-house or other regulations). furthermore you could specify the free parameters on the input masks >parameter-2< and on >parameter-3< - these are entered automatically when calling the program AQUACHEM.
also the free parameters will be controlled.
