<div dir="ltr"><div><div>Hi,<br><br></div>Currently ParaView assumes that all field variables have the same interpolation/shape functions for point data. You would have to either throw out the higher order interpolation/shape functions or compute the dofs for them for the lower order field approximation.<br><br></div>Regards,<br>Andy<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Dec 9, 2014 at 9:55 AM, Teo Ioannis <span dir="ltr"><<a href="mailto:teojgor@gmail.com" target="_blank">teojgor@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">I would like to ask if it is possible to display scalar, vector or tensor values at distinct nodes in a finite element mesh. <div><br></div><div>To make things clearer, there exist finite element formulations where not all nodes have the same number of degrees of freedom.
