Hi forum,

I just started a RGibbs simulation of a coal gasifier with Aspen Plus and received this error:


->Processing input specifications ...

* WARNING IN PHYSICAL PROPERTY SYSTEM
PARAMETER PC/ELEMENT 1 (DATA SET 1)
UPPER BOUND VIOLATED FOR COMPONENT CHAR
VALUE = 0.22300E+09, UPPER BOUND = 0.10000E+09

* WARNING IN PHYSICAL PROPERTY SYSTEM
PARAMETER FREEZEPT/ELEMENT 1 (DATA SET 1)
UPPER BOUND VIOLATED FOR COMPONENT CHAR
VALUE = 4300.0 , UPPER BOUND = 4000.0


Unfortunately, I dont find any information about this error, does anybody know what it means? I use PR-BM as suggested by Aspen for coal gasification.

(And just preventative: Does anybody know a good list of all errors in Aspen Plus? I know the help files provide some, but I didn't find this one in there for example...)

Thanks a lot and best regards,

Mat
