You can add heat transfer coefficient as a required output by selecting the same in data file quantities. You can find this option in file menu in fluent.

Average heat transfer coefficient on the interface of solid-liquid can be obtained from the Fluent->Reports->Surface integrals -> Facet average -> select the interface plane -> heat transfer coefficient and calculate or save the parameter as output variable.

It's calculation available in my research work and it's available in shod ganga

by selecting the data file quantities in the setup when you do the calculation step.
