The steps for creating the simulation are as follows: 1. Create mesh in GMSH (File attached) 2. Convert GMSH to Nektar++ compatible format using NekMesh 3. Setup the session file as per problem statement (Session file attached). [image: image.png] I would appreciate any help that I can get with this in trying to understand the source of this error. -- Thanks Varun
