[Einstein Toolkit] #1599: CarpetInterp/waveinterp_2p tests constant in time initial data

#1599: CarpetInterp/waveinterp_2p tests constant in time initial data --------------------------+------------------------------------------------- Reporter: rhaas | Owner: eschnett Type: defect | Status: new Priority: minor | Milestone: Component: Carpet | Version: development version Keywords: CarpetInterp | --------------------------+------------------------------------------------- the test waveinterp_2p sets up initial data using IDWaveMoL (fom CactusExamples) using kx=ky=kz = 0. and slopet = 0.1. Ie the initial data is constant in space and has frequency 0.1. It then evolves this using WaveMoL and interpolates in space and time with CarpetInterp. Since the function is constant in space (exactly so, see eg the output in InterpToArray::array1d_vars[0]) the interpolation in space just tests roundoff errors. The second time derivative (array1d_vars[2]) should be zero and all we measure in the test is truncation errors on the level of 1e-9. This makes the test very sensitive to -Ofast, -O0, gcc vs. intel etc. and not a very good test. I would rather either use a Gausian wave for initial data so that there is some actual data in the result and not just numerical noise, or leave out the 2nd time derivative from the test data. The test fails due to significant errors in a virtual machine using ubuntu.cfg (which usies -ffast-math and -O2). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1599> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

It would be good if it produced a skeleton thorn that compiled. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1919> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#2022: thorn guide on et website links to pdf pages -------------------------------------+-------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit website | Version: development version Keywords: | -------------------------------------+-------------------------------------- This is a continuation #2010 which was about the thorn guide being missing. This one is about the link behind "Thorn Guide" on http://einsteintoolkit.org/documentation.html, namely http://einsteintoolkit.org/thornguide/ points to an auto-generated index page of a directory of pdf files. Instead of the correct HTML page for a table of content pointing to html pages of documentation. Likely requires web server access to fix. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2022> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

This logic should be implemented in sim setup instead, so that users can use the ET out of the box on supported OSes. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1917> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
