F-packing problem
 
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

rbb =

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

What should I set about the F- packing for die-casting? always use the recommended data?

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