I calculated the liquid fraction value for the PCM domain as the volume-weighted average liquid fraction, and it seems as if the results obtained from the UDF are almost correct. However, there is a difference between the liquid fraction value obtained from UDF and the Fluent Report definition, as can be observed from the data shown below.

Any idea why this difference is occurring? The modified UDF is given below.
