<p>Dear all,</p>
<p><br /></p>
<p>A while ago, I’ve initiated an internal project to export results from my Finite Element solver (mechanical and thermal FEA’s) and to visualize it into Paraview (<a href="https://www.paraview.org/pipermail/paraview/2017-November/041481.html" target="_blank" rel="noopener noreferrer">https://www.paraview.org/pipermail/paraview/2017-November/041481.html</a>); but I was quite overloaded and this topic has been postponed.</p>
<p><br /></p>
<p>Currently the format of my the solver is not a part of the list (<a href="https://www.paraview.org/Wiki/ParaView/Users_Guide/List_of_readers" target="_blank" rel="noopener noreferrer">https://www.paraview.org/Wiki/ParaView/Users_Guide/List_of_readers</a>), and I’m thinking about the strategy to get the results, to perform additional calculations, and finally to post-process it into Paraview.</p>
<p><br /></p>
<p><em><u>Nota</u></em>: I’m using 2D and 3D meshes, structures and unstructured ones, with different element orders, and different type of results (nodal values and/or cell ones).</p>
<p> </p>
<p>Some of the following questions have probably ever been asked, but:</p>
<ol>
<li>What is the best format to create a result file readable by Paraview, especially for huge file? after some readings, VTK XML format seems to be the most interesting (parallelization capabilities) compared to the legacy VTK one, am I right or do ou have any other suggestion?</li>
<li>I’m still trying to figure out if xdmf and/or hdf5 format are relevant, and if they are relevant for my application: any feedback on it?</li>
</ol>
<p> </p>
<p>The workflow I’m imaginating sounds like:</p>
<p> Intermediate calculations</p>
<p> ^</p>
<p> |</p>
<p>Raw data (ascii file) from my solver --> intermediate file in xdmf or hdf5 format --> Paraview input file (depending on the reader)</p>
<p><br /></p>
<p><br /></p>
<p>Any feedback, advice and suggestion will be highly appreciated</p>
<p>(I’m quite new with Paraview)</p>
<p><br /></p>
<p>Regards</p>
<p><br /></p>
<p>Paul</p>
