Issues with mesh order - Pb with mesh Nodes or Elements : 8
Hello, I have used several times gmsh(version 4.11.0, November 6, 2022) with Safir (version 2022.b.3 and 2019 also) and I have noticed a small bug with the mesh generating order. When I have created my 2D geometry, I always go in Tools--> Options --> Mesh-->General and I put a mesh order of 2. However, when later I generate the mesh (using the command 2D mesh) I always have a mesh where elements have order 1. Then if I use the command Set order 2, the mesh is finally of order 2, but I cannot generate the .IN file and the error displayed is :_ Pb with mesh Nodes or Elements : 8_. I have also noticed, that a Refine by Splitting decrease the element order. Can you provide me some helpful explanation for managing this issue ?
Thanks a lot for advance
Best regards
