Hi Jean-Claude,<br><br>The clump finder calculates the total gravitational potential energy for a single clump but does not give you the potential field over the grid.  This is something that is calculated during enzo and it may be possible to get it written out as a field of which you can then make profiles.  I suggest you contact the enzo users list to see how one can do that.<br>

Dear all,<br>
<br>
I would like to access the gravitational potential and plot its radial profile. Matthew told me that it was done in the clump finding algorithm but I don&#39;t know how to use it.<br>
I would really appreciate if someone could help me.<br>
<br>
Thanks a lot,<br>
<br>
Jean-Claude<br>
