Re: Help




- In your manual you stated that solution fraction for invers modeling for
two
solutions  should be 1:1 . I have got solutions fraction more than this
ratio
i.e 3:1 or 2:1 .

Then you are evaporating or making hydrated minerals.


- In invers modeling , how we can define type of phases ( Dis/Prec)?

Each phase in -phases may be defined to dissolve only (dis) or precipitate
only (pre), see the manual.

- I leave it without defition . Also i leave force option without
definition.

"force" is rarely used.

- And  used  the first model to define the phases (prec/dis) in the new
Invers
model . It is correct way to define phases type.

Probably not. Define pre/dis depending on saturation index or knowledge of
your system.
