Hello all, in case someone can comment on this issue with the CarpetHDF5 VisIt reader that was brought up on the visit-users list recently. You can see the email thread here (it contains more information in particular the output of running VisIt with -debug 5): https://elist.ornl.gov/pipermail/visit-users/2014-December/016825.html and the mailing list address is visit-users(a)elist.ornl.gov Yours, Roland -------- Forwarded Message -------- Subject: [visit-users] Mesh plot : Carpet Multipacth Date: Mon, 15 Dec 2014 13:37:21 +0200 From: Dumsani Ndzinisa <g14n8326(a)campus.ru.ac.za> Reply-To: VisIt software users community <visit-users(a)elist.ornl.gov> To: VisIt software users community <visit-users(a)elist.ornl.gov> Hi All, I wonder if anyone has worked with CarpetHD5 data (plugin) to create a Multipatch mesh plot ("Mesh - Carpet Multipatch")? I'm trying to create such a plot, and it seems to be available on the Mesh plot options. However, VisIt return an error (error message shown below): The compute engine running on [host] has exited abnormally. Shortly thereafter, the following occured... The Mesh plot of "Carpet Multipatch" for the file "admbase::lapse.h5" could not be generated by the compute engine on host "localhost". Any ideas will be highly appreciated.

Einstein Toolkit Meeting Reminder
by Frank Loeffler 15 Dec '14

15 Dec '14

Hi Please consider joining the weekly Einstein Toolkit phone call at 10 am US central time on Mondays. As usual, you can find instructions how to join on the following web site: http://einsteintoolkit.org/community/support/ In short: the number is (+1) 225-578-4942 and the conference id is 118682#. As you can see above, the toll-free number was discontinued. I am investigating alternatives. Too many tickets have been worked on since last week to be mentioned here (>~60). Most but not all on the other hand was ticket-maintenance. If you are interested in one of these (or any other) issue, the next call would be a good opportunity to raise your voice. Also, I would like to point to currently 6 tickets in "review" state, waiting for someone to approve them [1]. The main trac wiki page has also been re-ordered [2]. This call will also be the last for this year, with the first in 2015 scheduled on Jan 12th, usual time and place. In case you cannot join the call, let me wish all of you already here a merry Christmas and a happy 2015. Frank Loeffler [1] https://trac.einsteintoolkit.org/query?status=review&col=id&col=summary&col… [2] https://trac.einsteintoolkit.org/wiki

Wv reconstruction issue for PPM+Poly EoS
by Hee Il Kim 09 Dec '14

09 Dec '14

Hi, Even though it may not be popularly used, Wv-reconstruction for PPM+Polytropic EoS doesn't seem to work properly. It gives significantly different result compared to the one with velocity reconstruction. I have seen at least the followings are fine; 2nd order ENO + Poly EoS (cf. crashed with 3rd order ENO) PPM + Ideal Fluid EoS 5th order WENO + Ideal Fluid EoS (cf. No poly EoS supports in WENO) The tests have been done with Herschel and partly with Noether. Cheers, Hee Il

An ET Trac Ticket Describing How to Register on the ET Trac System
by Zach Etienne 08 Dec '14

08 Dec '14

Hi all, I want to submit a ticket, so I clicked the "Issue Tracker" link on http://einsteintoolkit.org/, and was redirected to https://trac.einsteintoolkit.org/. Then I tried to set up an account. There was no link to "Register", so I clicked "Login". No option to "Register New Account" was found there, either. Thus I would like to submit a trac ticket requesting that there be some link to instructions as to how to register on the trac system, on the trac website. Alternatively, clicking "Issue Tracker" could redirect to a page with instructions, as well as a link to https://trac.einsteintoolkit.org/ -Zach * * * Zachariah Etienne Assistant Professor of Mathematics West Virginia University
