I have a problem in following Tutorial 4 where I got stuck at step
number 76. The tutorial says that the simulation ended correctly if
the last lines of the .LIST file should look like this:
Run end date and time (yyyy/mm/dd hh:mm:ss): 2018/10/25 11:31:05
Elapsed run time: 4.261 Seconds
However my .LIST file looks like this (attached): DATA IDENTIFIED AS GCD
OPENING FILE ON UNIT 99:
Therefore, I assume that the problem is in the well file so I did not
include the well package when choosing the Activate Packages in step
68-69. With this, the model run, but I need to include some wells in
the model. Could anyone please help me with this? I have attached the
.LIST file and well.IPF file below.
We experienced the same issue with Tutorial 4.
An IPF file should be in ascii format. However, iMOD itself saved
the IPF you created in step 51 as a binary file. This gives a conflict
while running the model. This issue will be fixed in the next iMOD version.
For now you can use the prepared IPF file that comes with the
installation of iMOD. You find the file as D:\USERS\RAHAJCY\IMOD 4_3\tutorials\TUT_Initial_Modeling\WELL.IPF
Thank you for your reply. I followed your suggestions right away and
the model worked! But how would you suggest if I would use my own
points of wells in this kind of model?
My colleague used iMOD version 4.2.1 and he did not have the same
error as we had with Tutorial 4. Would it be possible for me to
download iMOD version 4.2.1?
That is correct, version 4.2.1 performs well on this aspect. However,
we advise to use version 4.3 while it contains new but also
updated/fixed features. If you like to use you r own data to create an
IPF file there are at least 2 options:
- 1. You can use iMOD to create the IPF file by hand. To do so, use
the option "Edit - create features - create a gen". It has
also the option to draw points and save them as an IPF file (see
- 2. If you like to create an IPF file not by hand, use another tool
to create the file according to the format requirements described in
the manual (chapter "9.7 IPF-files"). I myself prefer to use
Excel (save as csv format) or a Python/fortran script.
Thank you for your suggestions. I would also like to try to use a
.csv file to create an .ipf file.
Hope you have a good day!
May I know when will the next version of iMOD be released? Because
iMOD is super important to my research time schedule.
Thank you in advance.
I'm interested in the topic of your research and the way you use
iMOD. If you like, please share some of the objectives / approaches
(you can use: frans.roelofsen - at- deltares.nl.)
You ask for the next iMOD release. There is no strict planning yet.
As a minimum we release 2 versions a year. The last release (4.3) is
dated december 2018. So it will take some more months for the next one.
For the issue we discussed (about the IPF file) we now found an
elegant solution by using Create GEN. When transforming your own
pointdata into IPF file, the use of Excel is common and recommended.
My conclusion is that version 4.3 is still applicable for you
research. Do you agree or is there an additional reason to look
forward to the release of the new version.
I have sent you an email to frans.roelofsen -at- deltares.nl for a
further discussion. Hope we can continue this correspondence via
email. Thank you.
