[Nek5000-users] termination of simulation at high reynolds number

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

Dear Sir

I am currently running a simulation related to oscillating airfoil.
Whenever I increase the reynolds number (>10000), the simulation stops
running after few time steps showing the statement as shown below:

Step   1652, t= 4.4604000E-02, DT= 2.7000000E-05, C=  2.938 4.2779E+03
3.4404E+00
