To show the problem, I modeled a cubic domain and meshed it into 8 elements. If the mesh order is less than 5, everything is ok. However, if higher than 5th order mesh is generated, the connectivity matrix does not include all the nodes in the element. In fact, some nodes are repeated in each element. </p><p style="margin-top:0px;margin-bottom:0px;color:rgb(0,0,0);font-family:Calibri,Arial,Helvetica,sans-serif,EmojiFont,"Apple Color Emoji","Segoe UI Emoji",NotoColorEmoji,"Segoe UI Symbol","Android Emoji",EmojiSymbols;font-size:16px"><br></p><p style="margin-top:0px;margin-bottom:0px;color:rgb(0,0,0);font-family:Calibri,Arial,Helvetica,sans-serif,EmojiFont,"Apple Color Emoji","Segoe UI Emoji",NotoColorEmoji,"Segoe UI Symbol","Android Emoji",EmojiSymbols;font-size:16px">I've attached the .geo file and the .msh file (6th order element).
