      Can you please explain the question? Can you please insert images as we can not download attachments. 


      If you want to coarsen the mesh then you can do it in workbench meshing by increasing the sizes. 


      You can check this video. 



      If you want to do it in Fluent then you can convert mesh to poly with Setting up domain - Mesh - Make polyhedra

      We can also increase the element size by adapting the grid. In R19.2, Fluent has dynamic mesh adaption. With this we can either increase or decrease the mesh.

      That looks like the Dam Break tutorial: 

        Assuming you're using 2019 you'll need to figure out the Adaption tools as the panels are slightly different.
