The more complex a model becomes an increasing number of coupled
quantities has to be managed where each of them may have a different
characteristic. For instance combining mechanical equations with
diffusion mechanisms (e.g.*epitaxie, oxidation*) implies two
completely different characteristics of the quantities. Very small
displacements with quasi linear behavior on the one hand and dopant
distributions with a magnitude order of 20 and more in comparison to
elastic strains on the other hand are a possible scenario which has to
be coped with. Both quantities need special treatment in case of
interpolation and Newton iteration. Therefore each quantity can be
*scaled* reflecting its characteristics:

*linear scaling*: all interpolation methods and update modes are adjusted to linear quantity characteristics (default)Scale(<QuantityName>) = Lin # use linear interpolation

*logarithmic scaling*: all interpolation methods and update modes are adjusted to logarithmic quantity characteristics:Scale(<QuantityName>) = Log # use logarithmic interpolation
