<div dir="ltr">Dear GMSH team,<div><br></div><div>Thank You for your free software. I am using this software for linux. Recently I am trying to mesh a 3d structure with tetrahedron elements of order 2. I am having 5000 elements which have negative jacobians! I am not able to understand the gui options and the tools, as I cant find any help on the gui options with the advanced tools any where. I checked it on your gmsh documentation and couldn't find help on that.</div><div><br></div><div>I get warnings, but I do not know how to view the elements that have these warnings!</div><div><br></div><div>At this point, i would appreciate any help you can give me. I have attached the geo file. All you have to do is click '3D' and 'set order 2' and watch the warning in the console. I tried guessing so many options! I even tried the optimization, but then either it crashed or I didn't get what I wanted! Please help me or point me to resources where I can determine how to solve this issue!</div><div><br></div><div>Thank You. We should start a forum within Stack to get help and support others!</div><div> <br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div><div>Regards,<br></div>Thej Kiran Ravichandran<br></div>2nd Year PME Master<br></div>TU Delft<br></div></div></div></div></div>
