Thank you very much Bastian

I will try your suggestions.
What i also did is to run a simulation (with mass transport and unsaturated flow) without the constraint (for the first time of the simulation) and after a while i added the min mass flow constraint and it's working well.
After a long period the solution will stabilizes so i think that this will have no impact on the solution.

Hello everyone

I'm running a 2D vertical model to simulate saltwater intrusion. It works fine when i'm running it in saturated conditions but when i add the unsaturated functions (van Genuchten) the model is converging very slowly and after a while (around 1000 days) the simulation stops
 
I'm using these boundary conditions (saltwater head: 0m, mass concentration: 35000mg/L, min mass flow constraint: 0g/d) on the seaside.
I'm starting with fully saturated domain and initial concentration of 35000mg/L at each point of the domain

When i remove the min mass flow contraint it's working fine.

Do you have any idea about what could be the problem. (ex :wrong initial conditions)


Thank you very much

Hello everyone,

I'm a new user with Feflow 6.1 and i'm running long simulations. I wondering if it is possible to determine the time necessary to complete the simulation

Thank you
