Hello everyone! I am quite new to PFC3D coding and still have some difficulties.

I am trying to simulate the application of seepage flow to the Representative Element volume of the levee. The problem is, previously I used CFD module inside PFC and specified the direction of the flow and its dimensions. For my current case I was hoping to keep GWL at a certain level and flow net as it happens in the soil banks. How should I proceed to solve the issue and is there any way to make it?

Here is the particle arrangement I have (size of the particles will change)
