<div dir="ltr"><div><div><div><div>Hi all<br><br></div>Thanks to Felix for suggestion. I was able to make 3D hexahedral structured mesh inside a sphere successfully. For sphere it is good to make a boundary patch and rotate it in all directions. I am attaching the code file for future users.<br><br></div><div>I noticed that it was not possible to make unstructured mesh as all the algorithms Frontal, MMG3D etc. were failing.<br><br></div><div>Deepak<br></div><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 10 May 2016 at 18:03, Deepak Garg <span dir="ltr"><<a href="mailto:deepak.garg@ingv.it" target="_blank">deepak.garg@ingv.it</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"><div><div><div><div>Hi all<br><br></div>I am trying to generate a hexahedral 3d mesh inside a sphere of radius 1.
