Hello All
I am simulating a GMO problem(coupled motion with fixed axis) with free surface, the two kinds of error messages listed below always confuse me, I am not sure the meaning of the errors and can do nothing about it. Can anyone help me?
Many thanks.
error in grmsch: 3 3 3
rba =
NaN NaN NaN
NaN NaN NaN
NaN NaN NaN

rbb =
NaN NaN NaN
NaN NaN NaN
NaN NaN NaN

============= mentor tip ===============
persistent f-packing location at t= 0.10573E+03
x= 0.12250E+01, y= 0.00000E+00, z= 0.84250E+01
i= 66, j= 2, k= 68
f= 0.92064E+00
temporarily holding pfpkc constant.
and reducing cfpk by factor of 10

The first error requires debugging of the solver and should be reported to the support people.

The second one is only a warning and may not be related to the first one. It is a common occurrence and is not usually a serious problem.

Thank you very much. But my software is unauthorized right now, so I think I have to tackle this problem by myself

Hello, everybody,
Can some one tell me what's the meaning of the f-packing coefficient?
I use this software in Die-casting.
