Hi Peter !

How are you doing?

thanks a lot for the support you gave me for the other problem.
theoretically, if I use steady state boundary conditions I would be
able to run the model in steady state (flow and transient), isn't it?
So, do you suggest to run the model with the configuration steady flow
and transient transport as you have shown during the course?

Thanks
Gio
