[Nek5000-users] Lid driven cavity using nek5000

Hello, I'm trying to solve a simple lid driven cavity problem with nek5000. I set up a coarse 3d mesh and prescribed the velocity for the lid according to Bouffanis et al. 2008 PoF (to ensure that there is no discontinuity between the lid and the walls),I'm getting a vanishing jacobian error. I'm not sure how nek solves, but for the moving wall do I have to prescribe the mesh velocity equal to the lid velocity or is there a way to specify that the mesh doesn't really move in time? Thanks for your help! -- Regards Shriram
