Message Related to Exceeded Minimum PDF Table Enthalpy in Partially Premixed Combustion Calculation

Why Do I Get the Message “Minimum PDF table enthalpy exceeded in …” when conducting Ansys Fluent partially premixed combustion calculation? Should this be corrected or is it ok to ignore this error?

When running a calculation using the Ansys Fluent Non-Premixed Combustion or the Partially Premixed Combustion model the following message may occur:
“Minimum PDF table enthalpy exceeded in 25 cells on zone 3.”

Please refer to the attached document below for solution to this problem.
