Any idea about thickness reduction warning in general contact definition?

Hello everyone,

Does anyone has any idea about this warning.

The thickness used in the general contact algorithm for elements in element set WarnElemGContThickReduce has been reduced. See the status file for further details.

The model is for impact analysis on RC beam under large mass intender. I have used contact pairs in general contact algorithm. The contact inclusions definition includes contact between intender and concrete and intender and rebars and self contact for concrete and rebars. Does this warning have any negative effects on the results?

With Regards
