<div dir="ltr"><div><div><div><div><div><div>Dear all,<br></div><br></div>Firstly, I am a Nek5000 newbie, so please accept my apologies for any daft questions!<br><br><br></div>- I have been working through the draft user guide, and am trying to view the the eddy_uv case using postx. Unfortunately the GUI seems to be corrupted, with missing text etc. (screengrab here: <a href="https://dl.dropboxusercontent.com/u/4391032/Nekton_001.png">https://dl.dropboxusercontent.com/u/4391032/Nekton_001.png</a> )<br>
<br>I am using Linux Mint with nvidia proprietary drivers, the problem seems to affect the other NEKTON tools (prex etc.) so I'm guessing it could be an X11 issue? Has anyone encountered this before? How did you fix it?<br>
<br><br></div>2) For meshing, I'm interested in fairly idealised, structured geometries, (e.g. impinging jets, boundary layers etc). I have a heap of existing OpenFOAM (hexahedral) blockMeshes already set up for LES. Has anyone managed to convert an OpenFOAM mesh to Nek5000? (Is it even possible to do this with a higher-order spectral code?) I was thinking about trying foamMeshToFluent, and then using the python script written by
