Least-Squares Upwinding disabled on v7.2?

Hi,

The option to use LS upwinding in v7.2 appears to be greyed out.

The problem is a vertical unconfined 2D aquifer with mass transport simulation.

How can I re-enable that option?

Hello Costal,

I just checked there is no problem when running in transient.

Are you running the model in steady sate? LS is not available for steady state.
