No longer taking this approach, so answer not actually needed (but still interesting!).

Hi,

Is there a way of representing a general head boundary in FEFLOW? With finite differences I am familiar with the process of defining a head at a fixed distance beyond the boundary and a conductance term. Is there an equivalent in FEFLOW?

Thanks.

I have been told that it may be possible to run two Feflow models simultaneously, where the boundary conditions in one model are determined by the output/boundary condtions of another model. Is there a way of doing this? It is most likely that I will want to use the flux out of one model to detemine the flux entering the other. How might I go about this?

Thanks,

The dimensionless value for 'Storativity' refers to specific yield. Storage compressibility in the unit 1/m defines the storage per meter head change. Both are not related to the aquifer or layer thickness.

Currently this cannot be done via the FEFLOW user interface. The only way for a direct feedback would be to use the FEFLOW programming interface IFM, writing a few lines of code in C or C++ and compiling the so-called IFM module into a dll.

It is WL < elevation of slice 2 when layer 1 is set to 'phreatic', the others to 'unspecificed'. In case of a 'free & movable' top, it is WL = elevation of slice 1 < original elevation of slice 2.

Yes, lots of users do so.

Hi,

I need to build a model where half of the domain is confined, but the aquitard pinches out and I need to model the other half as unconfined. What is the best way to go about doing this?

Also, how does FEFLOW deal with dry cells in unconfined layer? Is it ok to define layer elevations such that the water table may be below the bottom of the upper layer in places?

Thanks,

SB

There will be an IFM-like Python interface in the future. However, the Python option will not be contained in version 6.0 which as about to be released in beta.

It is not necessary to write your own code. You can implement a recharge function using the equation editor in FEFLOW. See http://www.feflow.info/320.html for an example.
