Flow 3d warning "cfpk"
 

my warning shows as follow.

============= mentor tip ===============
persistent f-packing location at t= 0.54719E+01
x= 0.50000E-01, y= 0.50000E-01, z= 0.50000E+01
i= 2, j= 2, k= 64
f= 0.81884E-01
========================================

recommend reducing cfpk by factor of 10

(1) is the warning important?
(2) what can i do to make such warning disappear?
(3) what does "cfpk" mean?

Search this forum for 'f-packing'. This question has been asked many times.
