Help me please

Hello everyone, I am a new user of feflow. I will like to know how checked that flow that I impose in my model is respected? ??? Thank you for your answers!

Hello,

you can use the "Budget analyser" menu after a model run.

Hello, Thank you zebra for your answer.
I have two other problem to solve:
1)For a vertical 2D problem with a free surface, which best the model(Genuchten or linear) to model the unsaturated zone?
2) to simulate  infiltration I imposed a 2nd kind of BC condition  but I see that flows are not uniform during the simulation. why?
Thank you in advance for your answers!

To calculate the total flow entered the model, I must multiplie the value given by the budjet analyzer by the depth of the aquifer?

Hello,

the budget analyser will give you a volumetric flow value. In a vertival 2D model FEFLOW assumes that your aquifer is 1 m thick. So you can scale these results to some other thickness easily.

To your question about Genuchten or linear model:
a linear model would not produce realistic results in the unsaturated zone, you should use a Van Genuchten type model. I have quiet good experience with the modified Van Genuchten model. If you have numerical problems during the computation you can adjust here the parameter for capillary pressure and relative permeability seperatly (low values of A and Delta should help to "smooth" your calculations).
