I can think of two ways to create a computational mesh for your application: 

1: Include both fluid and solid domain: You can mesh both the solid plate and the fluid region, if you want to solve for conduction in solid along with the convection (CHT). In this approach, you can see the temperature distribution in the solid body i.e., the flat plate.


2: Just include the fluid domain: You can just mesh the fluid domain and give temperature/heat flux as the boundary condition. 


If you are new to meshing, I would recommend you to go through this free comprehensive learning track on meshing using the Ansys Fluent Meshing Watertight Workflow: Ansys Fluent Meshing Watertight Geometry Workflow - ANSYS Innovation Courses


Thank you!
