Dear,  I'm working on a model in an alpine context. I've seen that results using free or phreatic surface are quite different. I applied a Cauchy BC to the river to simulate the interaction between the river and the aquifer.  Which mode would you recommend? The phreatic or the free surface surface? Regards, Lucien

Just find the solution! It has be done in the map panel.

Dear,  I've inserted a map (tiff) as a background in a model but it comes on top of other parameters I'd like to display on the map. Is there a way to move it backward? Thanks for your answer. Lucien

Thanks Carlos, I'll check the training. Best, Lucien

I'm working on a model of an alpine aquifer with a river partially connected. To model the relation between the river and the aquifer, I'm using the Cauchy BC. I followed the instruction of this post [https://dhigroup-support.microsoftcrmportals.com/knowledgebase/article/KA-01252/en-u], however I'm probably doing many things wrong as the result looks very weird Below is how I did the model: - select the nodes of the first and second slices of the mode (the first layer is about 10-20m thick) - assign a fluid transfer BC equal to the elevation (this what I guessed is the reference head) - assigned an In/Out transfer rate of 0.0001. After running the simulation, the elevation got distorted. Attached are printscreens of the model before and after the simulation. Any idea how to solve this?
