Hello,

I have tow question:

I want to simulate an excavation in feflow. I have a 3D model with three layer and four slices.

My first question is how to modulate the excavation. I don’t know if I put a seepage face in the bottom of the excavation or in the bottom of excavation and the slope of the excavation.

My second question is:

I want to determine the flow of seepage coming out of my model after excavation.

I don’t now how to determine this flow (budget analyzer or fluid flux analyzer)

I send to you a cross section of my model before and after excavation.

Hello,

When i run my model i see this message

PCG results in 1000 steps only a relative accuracy with an error 5e-8
value of beta:1.133e2 indicates an instable preconditioning


but in the iteration the model converge.

What means this error and the final result is true or no

Hello,

I want to modelize an impermeable boundary in  the interior of my model.

I use the 2 Kind of boundary conditions with a flux=0 m/d.

But the water pass through this boundary.

I don’t know how to modelize this boundary.

the simplest way is to use the specific option of the function copy.

to create the 10 slice you can do this by fixing the first slice(ground surface) and adding 9 slice.

Hello,

I have an unconfined aquifer. The thickness of the aquifer is about 30m. I want to divide this layer into 10 slices.

I must affect conductivity to all slices or there are other a simplest way to do this?

How to create a *. Trp file with Microsoft Excel ?

I want to simulate a drain. I think I will use the seepage face option with a max flux of 0.

i want to simulate the fresh water flow into tunnel in 3D.but i don't know how to make the modal using feflow?

I want to set up a model of a local or regional groundwater flow system for calibration. Afterwards i want to insert one or more excavations in this model to determine the flow rate that will enter this excavation and has to be pumped out. As well, i want to to determine the impact that the excavation has on the groundwater flow, especially the change of the groundwater table.

I don't know how to do this with feflow????
