Dear Colleagues A PhD student who is looking into geothermal possibilities at a location and who has collected a lot of data has contacted us. He needs to...
Hi Mr. Giovanni My model is saturated transient flow and contaminant transport with one river with transfer boundary conditions. Others boundary conditions are...
Hi Manish, Oscillations are common especially in complex models; whether they are important depends on the whether the oscillations decrease to values small...
it is hard to understand if it is problem or not. Can you provide more details of your model? transient or steady? and in the first case are the BCs transient...
Hi I am facing a problem in feflow. It is when i am running my problem, the graph of head values at various observation points is showing too many oscillations...
Greetings to you all, Download SRTM 90m Digital Elevation Data (Version 4.2) The SRTM Data now available from CSI-CGIAR SRTM Data portal. This is Free, and all...
Greetings to you all, This is an evolving drought monitoring tool, which, in its present form is based entirely on remote sensing data. It aims to supply...
Greetings to you all, Your online "Pocket Dictionary" for all your GIS, Remote Sensing and Spatial Hydrology FREE data needs… Also lots of Tutorials, ...
hi Our team are working at a project on seawater intrusion in China, and its the time to choose a proper software. Feflow, as our first choise, is definitely...
Hi giovanni Thank you but i do not have de cd program, so if you are so afable and send me the exercise I will be very thankful with you Bye Malena Lucen ...
In the program folder you can find examples and exercises: C:\Program Files\WASY\FEFLOW 5.3\demo while in the Installing dvd you can find all the manuals and...
hi everybody i desperate need a tutorial or some applications or examples using feflow, please if some have a file in pdf or word about this please send it to...
Thanks Pete. You are right, I figured out that Feflow interpolates the values at t=0 and t=730. As you said the only way to switch off the 1st boundary ...
Hi Gio, I searched my notes and manuals about this and came up with nothing. In all the examples I've seen, the first time is always zero, and I have been in...
Pete, I have a terrible doubt now. If I define a power function (for a head boundary condition for example) file like the following one ! ! t [d] fvalue...
Thanks Pete, As workaround I manage to generate some input files: one for the "power functions" and one for the "time variant ID". For the generation of the...
Hi Gio, I see your point. There's no way around it but you can create the node and power lists outside of feflow and edit them into an ascii fem. I've done a...
Pete, assigning a pressure condition or a head condition for feflow is exactly the same. Let assume (as in my case) I have to model a seepage, I would use h=z...
Odd, but you are right. On my first attempt, it seemed to work, but when I looked at the node with the inspector, it indicated the boundary condition was a...
I tried that When I use options->pressure instead of head I cannot define any time-variant function. It seems that is not possible to assign a time variant...
yes - it is done the same you would do with head, but select pressure as the variable of choice. under the mesh inspector, set the light blue button to...
It is surprising that some spam messages are being circulated in the group for past few days, though the group is moderated. I am trying to look into the...
Peter, I am not sure about oscillation. However, coarse discretization, especially in the vertical, definitely causes numerical dispersion in FEFLOW - at...

Here's one paper: http://www.imwa.info/docs/imwa_2008/IMWA2008_190_Ruehaak.pdf and another one: ...
I forgot something in my last post: For open-loop systems, you often would like to link the injection temperature to the abstraction temperature by applying a...
Monica, A too coarse discretization would typically lead to oscillations rather than high numerical dispersion. So please check whether your dispersivity...
Monica, Among other things, FEFLOW (like some other models) suffers from a large numerical dispersion. The simplest solution is to subdivide the domain into...
