<div class="moz-cite-prefix">Hi Magali,<br>
<br>
These are all good points but I did want to correct the point that
there are no known published work using coupled codes with
CitcomS. We had three papers, a plume study and two subduction
studies:<br>

We are currently not using the coupler in my group.<br>

</div>
<div>First, there are known issue with cookbooks (some only work
as shown with older version of CitcomS), </div>
<div>so this would be a good opportunity to update these. I
suggest soliciting very well documented contributions </div>
<div>from members of this mailing list, which they use when
starting their students on problems.</div>
<div><br>
</div>
<div>Second, I don't know of any published work using coupled
codes (please correct me if I'm wrong). While this was
demonstrated to work for some simple models and was a heroic
effort for those who made it work, its hard to get to work
in practice for more complicated problems. For example, if you
have higher resolution for a CitcomS model embedded inside a
larger CitcomS models with lower resolution - any thermal
boundary layer ends up creating thermal instabilities at the
sides of the box due to the mismatch in the thickness). If
someone is using the coupler, then we need to keep this
capability, but if after this much time no one has used it, that
is telling us something important.</div>

<div>I am also concerned about this development. The
cookbooks provided with the manual will only work if the
pyre version of CitcomS is installed. Will there be new
cookbooks developed? Or will they too no longer be
supported? These are valuable learning tools for new
users including graduate students. It would be a shame
if there were no longer educational examples for new
users to safely learn on.</div>

Subject: [CIG-MC] CitcomS Python Removal<br>

Hello,<br>
<br>
The CitcomS developers have recently decided to
remove Python and Pyre support from CitcomS.
There are several reasons for this:<br>
<br>
- The Python interface in CitcomS is not
compatible with Python 2.7 or above. Python 2.7
was released in 2010, meaning most systems set
up in the last 3 years won?t support Python in
CitcomS.<br>
- The interface requires downloading extra
packages - this happens automatically but can
cause compilation failure on some platforms.<br>
- The interface opaquely assigns some parameters
with values not controlled by the user.<br>
- The Python interface adds a level of
complexity making it harder to debug the program
and understand how data structures are
used/modified during a run.<br>
- Many of the major CitcomS users do not use the
Python interface.<br>
<br>
We plan to remove this functionality from
CitcomS and provide tools to convert Python
based input files to the normal input file
format. Relevant logic that was in the Python
framework will be moved into the main CitcomS
code. This change will be implemented over the
coming year and incorporated into a future
CitcomS release.<br>
<br>
If you have any concerns about this decision or
would like to weigh in, feel free to contact me
or the cig-mc mailing list.<br>
<br>
Thank you,<br>
<br>
-Eric<br>
<br>
