This LS-DYNA simulation shows a simple ICFD anisotropic porous media flow input deck. The flow entering the porous media is deflected and follows the orientation of the porous media.
This LS-DYNA simulation shows a simple ICFD anisotropic porous media flow input deck. The flow entering the porous media is deflected and follows the orientation of the porous media, the porous media is located between the two rectangular blocks.
