How i can know the magnitude of lift and drag force from ansys cfx?

Lift force is the force that acts perpendicular to the direction of motion, while drag force is the force that acts parallel to the direction of motion. In other words, lift force is responsible for the upward motion of an object, while drag force is responsible for the resistance to motion.
Lift and drag force can be calculated using the pressure and shear stress values obtained from the CFX results. The lift force is calculated by integrating the pressure and shear stress values over the surface of the object, while the drag force is calculated by integrating the shear stress values over the surface of the object.
Yes, ANSYS CFX has a post-processing tool called the "Force Monitor" which allows users to visualize the lift and drag force acting on an object in real-time. This tool can also be used to plot the variation of lift and drag force with respect to time.
The geometry of an object can significantly affect the lift and drag force acting on it. A streamlined or aerodynamic shape will experience less drag force compared to a non-streamlined shape. Similarly, the angle of attack and surface roughness of the object can also affect the lift and drag force.
There are several ways to reduce drag force in ANSYS CFX simulations. These include using a more streamlined geometry, increasing the angle of attack, and reducing the surface roughness of the object. Additionally, using turbulence models and optimizing the mesh can also help in reducing drag force in simulations.
