[Nek5000-users] Axisymmetric jet using genbox

[nek5000-users at lists.mcs.anl.gov]

Dear Nek users,

I am doing my master thesis at Technical University of Madrid and I am 
using Nek5000 to study an axisymmetric jet.

I have generated the mesh using genbox. Then I have try to run numerical 
simulations:

1) 2D
2) Setting: IFAXIS T
3) Setting: IFAXIS T, IFAZIV T (and with IFHEAT T, to plot the azimuthal 
velocity.

In all cases my simulation crashes, due to some problems in the boundary 
(I have tried with both ON and O BC)

So, I have added artificial viscosity, but the axysimmetric simulation 
(case2 2 and 3)  still  crashes:


       3.000000         p99    dealiasing:if <0 disable
       0.0000000E+00     p100 reserved
       1.0000000E+00     p101   No. of additional filter modes
       0.0000000E+00
       1.0000000E-02     p103   weight of stabilizing filter (.01)




Could you give me any recommendation to follow?

Thank you in advance.
