DUE TO SHORTAGE OF SPACE I COULD NOT EXPLAIN THE EXPLAIN PROBLEM,

THIS PROBLEM DEFINITION KINDLY HELP

 The plate heat exchanger is made up of orthotropic –graphite material and having biaxial K created 2 domains a fluid domains representing water in either side of the plate , a solid domain representing the plate. Since 2 different domains had to create a Solid -Fluid domain interface.  like to make a conjugate heat transfer between fluid and solid.Can anyone guide me how to create fluid-solid interface for this problem using Ansys fluent.
