While running simulation with hooked udf DEFINE_SR_RATE in fluent Warning..Surface chemistry solver did not converge for NNNN cells/faces warning coming after each iterations . The number NNNN got changing after each iterations with out any trend.? Why this warning? And the residuals are also not converging even adjusting the under relaxation factors.
