<div dir="ltr">Hi Tanmoy<div><br></div><div>thanks for the quick answer, unfortunately I didn't commit this kinds of errors. I have already used my matlab routine for other cases and it worked well, so I'm pretty sure that there isn't errors. The only differences is that I'm using this routine to interpolate the <a href="http://hpts.in">hpts.in</a> points on more complex grid and on a turbulent field. It seams that I have the Runge's phenomenon. Is this possible with the hpts routine?</div><div><br></div><div class="gmail_extra"><div class="gmail_extra">Sincerely</div><div class="gmail_extra">Alessandro </div></div><div class="gmail_extra"><br></div><div class="gmail_extra"><br></div><div class="gmail_extra"><br></div><div class="gmail_extra"><br></div><div class="gmail_extra"><br><div class="gmail_quote">2015-11-20 17:29 GMT+01:00 <span dir="ltr"><<a href="mailto:nek5000-users@lists.mcs.anl.gov" target="_blank">nek5000-users@lists.mcs.anl.gov</a>></span>:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr"><div>Hi Alessandro,<br><br></div>I use exactly the same procedure for my case.

Using Matlab I built an <a href="http://hpts.in" target="_blank">hpts.in</a> file that contains the points of a structured and not constant mesh, then using Nek in postprocessing mode I evaluate the values of velocity an pressure in this points. When I reshape the hpts.out in order to visualize my domain, there are many zones that have no-sense values!. I performed the same interpolation in tecplot and it works fine. </div><div><br></div><div>my question is: there's any way to perform a first order interpolation in Nek5000? <br></div><div><br></div><div>Sincerely</div><div>Alessandro </div></div>
