Dear all,
I have recently downloaded Nektar++ 4.3.0 and started doing the examples as shown in the user guide for the incompressible Navier-Stokes solver.
I am having some problems trying to reproduce the results of the "Turbulent Channel Flow" (TurbChFl_3DH1D.xml). The simulation runs without issues, but after
converting the final .fld file to .vtu for visualization in Paraview, I still see a velocity field equal to that of the initial condition (u = 1 everywhere except near the wall), instead of the expected turbulent flow.
Has anyone experienced a similar outcome? Maybe I have to change something (simulation time?) in the .xml file before running the solver?
Thanks,
