When the genbox reading the .box file, the error says 'fortran runtime error: end of file' occured. I had a relatively complicated computational domain so I divided it into 14 boxes. I wonder if the number of boxes is too large that genbox cannot deal with them. Before that I tried 8-box case and it ran well.

Thus my question is: is the perturbative formulation (npert=-1 in *.rea file) for low mach number already implemented in nek5000? If not, is there a simple way to do this?

However, if the mesh is a bit more complex, let's say two rectangles, one bigger than other, the routine n2to3 also works, but genmap gives the problem showed below (the 2d mesh perform 2d numerical simulations properly, in addition if the extrution is planar instead of circular, both n2to3d and genmap works properly and also Nek5000) Is there anything I am missing about n2to3 and the circular swept?

So i have tried two different setup, one with much elements and N=4 and one with less elements with N=8. With the first setup, the run is fine, at high Re i have turbulent flow, but i have restart issue and very low performance. If i launch the second run (high order) with the same setup of the first run (low order) i have a laminar flow. Another try done was to run over another machine with more power first setup (same elements ) and increasing N since 4 to 7. I expected a turbulent flow too, instead i have another time a laminar flow. My decision to decrease elements number and increase N, has been taken to following some answers in your mailing list archive to increase performance. So, which could be the causes of this strange behaviors? Another question is, how can i increase performance for this very small machine? I already wrote i changed number of elements and N, i fixed too time step, gmres = 40 in SIZE, Helmotz and Pressure tolerance to 1 E-8 and 1 E-5 and activated projection (param 94 and 95 equal to 5). There is something else that can i do? Best regards, Federico.
