[Nek5000-users] A Restart Issue with NaNs

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

Hi, 



I am having an issue with a simulation in which I restart using the restart options in the Rea file. At the very first time step 

I get NaN's in the Helmholtz VelZ .  I have done several restarts of the same simulation at earlier points to arrive at where I am at 

now, however I get this upon trying to continue the simulation further.  



Any ideas on why this could be, or how to troubleshoot it?  I'm not sure what I could do since this is showing up on the very 

first time step. 



Thanks a lot, 

Michael
