the version 5.3  can plot measured head versus computed head for the wells at a
particular time period.

   i have a doubt

   How to get the plot of  measured head vs computed head for a well during
various time periods.

   is it possible

I remembered that with the version 5.0 and 5.1, one can plot the hydrograph
by using a free IFM that is developed and downloadable from wasy’s website
(www.wasy.de).  I am not sure if it is still available in the new version,
but I think it should have some function like that.

About the second question, I am not sure if I understood it correctly too.
If he means to assign the point aquifer property obtained from the scatter
boreholes, he can prepare a pnt file, and do the interpolation for the whole
model domain. But the quality of the interpolation will depend on the
numbers of data points and how large of the model domain.

You have to export *.dar files in the postprocess of your model and to plot

Hi averybody!

I would like to know how to work in feflow with field data in order to
calibrate the model...

Could the programm automatically assign the flow materials values from
different observations field points?

Thank you.

Dear all,

Is there anybody who can help me to import a mesh in FEFLOW?
I had previously generated a mesh with another program and now I would
like to import it with FEFLOW.

Thank you for your help

Giovanni

Dear all,
is it possible to export the supermesh in dxf format?

thank you

Giovanni

Sharlene,

You find all the FEFLOW manuals on
on http://www.wasy.de/english/products/feflow/doku.html

Especially the Reference Manual and the White Papers Vol. II contain
detailed information about density-dependent simulations (seawater
intrustion) and how FEFLOW handles these.

For additional and more detailed questions, you might also contact the
FEFLOW support team (support@...).

Best regards,
Peter

WASY GmbH

Dear Sharlene,

I think, first of all, you must read any good book(s) on "Groundwater
Modelling". To begin with, you can refer "Introduction to Groundwater
Modelling" by Wang & Anderson.

For more details on seawater intrusion, you can refer the
book "Seawater Intrusion in Coastal Aquifers - Concepts, Methods and
Practices" by Jacob Bear and others.

Best Wishes
Kumar

Hi! I would like to ask if how thus FEFLOW works. Because i'm doing my
thesis about seawater intrusion on acquifers and my adviser is
requiring me to come up with a model. Can anyone help me about this
matter? Can I have a copy of those research study that is related to

Peter,

another question: in the definition of the transport material I do not
understand the meaning of "Porosity". Is it the total or the effective
one? In the on line help it seems to be the effective in the user's
manua in the table 5.3 at page 69 it is described as the "void space"
that is the total porosity for me.

Thank you

For finding additional information about the software and discussing
with other FEFLOW users, you might also join the WASY Web Forum
(http://www.wasy.de/forum).

I hope you'll enjoy your work with FEFLOW!

Peter
WASY GmbH

Hi Giovanni,

the pathlines you see are pathlines calculated on a 3D velocity field
projected to the current slice. You don't see which ones leave the
layer and which stay in the layer. However, you can use 3D particle
tracking via 3D options - Pathlines to see the pathlines in 3D and
project them both vertically and horizontally.

Cheers,
Peter

I am so glad I've found the group, since in Mexico, where I live is relatively
unknown, so I inmediatly started to fill the registration.

   I am new in Feflow, but in the last 2 weeks have been "playing" it
intensively, and I find it as a very powerful tool for simulations. I am more
focused in groundwater flow simulations.

   So, I will be asking every now and then and hopefuly  in short time I would be
able to help others.

   Please feel free to send me a message at any chance I will ve very pleased to
have contact with others Feflow users.

   I am guessing if there are levels within the group, how does it work? any
advice is of great help.

   Thankyou

   Berenice

Dear all!
I am sorry to bother you with my questions but as new user of this
powerful program I am not able to understand some things.
in this moment I am trying to understand the results related to
"particle tracking". In particular I would like to understand if the
flow lines I can see in the plane (slice) I choose represent the
projection of the 2D streamline or they represent only the path they
do in that plane. In the first case is it possible to differenziate
the color of the streamlines that go up or down as in modflow?

thank you very much

Giovanni

Hi !
I have a doubt . When I want to insert a well in a 3-d domain should I
assign the disharge on the top or on the bottom of the well screen ? I
thought it was better on the bottom, in this case I dont have to be
worried if the water table goes down below the elevation of the node
where I assigned the discharge, but I saw the example exercise of WASY
and they assigned the disharge on the top.

Thank you very much

After examining the above message and list of members, I found that
"basinsinfo@..." has been subscribed as a member of this list, though
it seems to be posting address for "basinsinfo" mailing list hosted by epa.gov.
So whenever, a message was posted to this group, it was automatically being sent

Any way, I have now removed "basinsinfo@..." from the list of members.
It should resolve the problem.

Dear All!

I am sorry for the last email. I have finally found the answer to my
solution. When I run the modflow model I assigned a liner gradient
along the downstream side (the equivalent freswater head), but
apparently seawat transforms the salt head in the fresh head
automatically and it is not necessary to assign a liner gradient as in
Feflow. I tried to run again the new model and the two solutions
(feflow and modflow) now match very well.

Thank you again for yoyur attention
Gio

Hi to evrybody !

Is there anybody who can explain me the results you can see in the attachment?
(attachment not allowed in this group - Moderator)

Could you suggest me an analytical solution to compare with the numerical ones

For both of the model I have used a sqaured mesh grid. the size of any
element was 5x5 m.

thank you in advance

Giovanni

Hi Giovanni,

FEFLOW does not save the optimal configuration. You can check the
parameter set after the PEST run, and if you want to keep it just save
the model (maybe with a new file name).

Cheers,
Peter

Hi to evrybody !

I tried to use the parameter estimator module to optimize the
evaluation of the conductivities and I have succesfully run a model
with it. The problem is that I cant understand where the program saves
the "best" configuration (that one which minimizes the objective
function).
When I try to access to the problem editor form the run section
everything seems to be ok and I could see the new K zones. If I try to
load the output file (the dac file) from the "postprocess" panel I
notice something strange in the K zones I have defined. They are not
the same I saw in advance and the conductivieties are not spatially
homogeneous within the areas I have defined. Have you ever noticed
something like that? What is wrong with my apporach?

Ciao

thank you again for your support. I thought was possible to do that
with pnt files too as I could import the labels during the
construction of the supermesh. By the way thank you again for the

How did you import the files (from wich source). I used SHP files and I never
