i am trying to produce result of a paper in which they analyzed flow for different darcy number but i dont know how to put different darcy number in ansys. also the nusselt number is not matching neither the streamline. have yoy previously worked on porous media in ansys?

The paper which i am following:
Analysis of momentum and energy transfer in a lid-driven
cavity ®lled with a porous medium
