Hi all, I'm having some difficulty in running a simple 3D simulation on Nektar. I have run several 2D cases and they work perfectly. However, whn I try to launch a 3D case the solver fails immediately with a segmentation fault. PFA the case example I'm trying to run. It is a simple box geometry with inlet, walls and outlet defined. I'm using NekMesh to convert the .msh file to the .xml file requred by Nektar++.
