Hi! :)

I'm almost done with my thesis model (yay!) and I'm now addressing the water recharge issue.

My idea is to make from element selections (shown in attached picture), element groups, so I can make a mathematical expression for recharge based on lithology. Is it possible? and how?

I'd love to do something like Q=m*Z+n but with 'if' statements based on lithology. So in summary it'd be like:

if group==rock1: Q=m1*Z+n1
else group==rock2: Q=m2*Z+n2

Is it possible to make it?

Update: I know it is matter in this case to select and apply different equations, but I think this 'if' feature in FEFLOW has a lot of potential.

Kind regards.

The grouping can be done in an elemental user data distribution. It does not support strings ('rock1'), but you can encode your rock types in float numbers (1.0, 2.0, ...) and apply the 'if' statement to those.
