Hello everyone,
For now, I am using FEFLOW version 7.4 to simulate groundwater flow to the drain, but I have a problem, so I try to build a box model and figure out this problem; please see the attached picture and help me.
I built a model with boundary conditions like the picture below.
And I want to assign the Cauchy boundary as a Drain boundary, so I assigned the In-transfer Rate = 0(1/s) and Out-transfer Rate = 99999 (1/s) to only let water flow from the aquifer to the boundary.
Although the In-transfer Rate assigned = 0, it still has the water flow from the boundary to the aquifer.
Please help me with this problem, I have tried many ways, but I figure out that the "Transfer Rate" does not care about "In-transfer Rate" or "Out-transfer Rate." How can I assign the Drain boundary condition for the model?
For more information on Drain boundaries, please visit this website.
