<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body style="overflow-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">Hi all,<div><br></div><div>I am starting to learn the use of CarpetX and for this I started using the WaveToyX thorn. I wanted to ask for guidance for three problems that I have encountered so far, all of them related to the output data:</div><div><br></div><div>1) I wanted to get 3D data, for example in .tsv format. Here I realised that there is an ambiguous definition in the documentation for the parameter “out_tsv”, which in section 12.1 it says to control TSV output and have default value “yes”, but in section 14 it says to control the 3D output in TSV and have default value “no”. This last behaviour is the one that I encounter when running the parfiles. </div><div><br></div><div>2) When I set up “<font color="#000000">out_tsv" to “yes” and “out_tsv_every” to a number, for example = 16, I get 1D output every 16 iterations, but 3D output in every iteration, therefore I suspect that “out_tsv_every” is only controlling the frequency of the 1D output, and I cannot find a way to control the frequency of 3D output.</font></div><div><font color="#000000"><br></font></div><div><font color="#000000">3) I attempted to output data in HDF5 format but I did not succeed. I first set the parameter “openpmd_format” to “HDF5” and also set “out_openpmd_vars” to the variables that I wanted, but I got an error in the first iteration:</font></div><div><font color="#000000"><br></font></div><div><pre class="code highlight" lang="c" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><span class="n">INFO</span> <span class="p">(</span><span class="n">CarpetX</span><span class="p">)</span><span class="o">:</span> <span class="n">OutputGH</span><span class="o">:</span> <span class="n">iteration</span> <span class="mi">0</span><span class="p">,</span> <span class="n">time</span> <span class="mi">0</span><span class="p">.</span><span class="mo">000000</span><span class="p">,</span> <span class="n">run</span> <span class="n">time</span> <span class="mi">1</span> <span class="n">s</span>
