[InputGmsh] - Element dimension : 2 [InputGmsh] - Space dimension : 1 [InputGmsh] - No. of nodes : 2211 [InputGmsh] - No. of 2D elements : 2000 [InputGmsh] - No. of boundary elements : 420 [InputGmsh] - Elapsed time: 0.00769036s. [OutputNekpp] Writing Nektar++ file 'mesh.xml' Fatal : Level 0 assertion violation Coordinate dimension should be at least 2 for a 2D geometry terminate called after throwing an instance of 'Nektar::ErrorUtil::NekError' what(): Level 0 assertion violation Coordinate dimension should be at least 2 for a 2D geometry Aborted (core dumped) NekMesh does not read the correct space dimension for some reason. The mesh was created with ICEM, exported as cgns and converted to msh format with Gmsh version 4.5.2. I use this approach regularly and this is the first time this issue showed up. Any help will be very much appreciated! All the best Alex Sicher versendet mit [Proton Mail](https://proton.me/mail/home).
