Force Report Definitions

      Hello,

      I am using LES with the WALE subgrid model (FLUENT 2019R3) and would like to know exactly how the "drag force" in the "force report definition" is calculated. I spent some time searching the Ansys Fluent Help document and found the information below. I would like to (need to lol) know exactly how Fluent calculates the viscous and pressure forces. Any help is appreciated.

      Hi,

      Drag forces in the report definition is calculated as 1/2*rho_ref*V_ref^2*area_ref.

      Thank you.
