Hi Steven,
No problem. I recommended to turn on the consistency flag (CONST = 1) if you are running in the SMP mode, which helps summations in calculations to occur in a precise order from run to run and lead to identical results (or nearly so) independent of the number of processors.
You might be asking when we can turn off the consistency flag. The answer is with the consistency option off (CONST = 2), the computation time will be less, and the solution is achieved faster (Check out the variable “CONST” in *CONTROL_PARALLEL card in the LS-DYNA User Manual Vol I (URL: LSDYNA Manuals)). You can check how different the predictions are when using CONST = 1 and CONST = 2 and then decide if you prefer to save more time at the expense of losing some degree of accuracy or to have more accurate predictions at the expense of more computation time.
I hope this answer helps.
Thanks,
Pedram
