Hii

The 3D geometry contains a catalyst bed of 5 layers as shown in the attached file. How to specify inlet, outlet and wall for this geometry? Water and Nitrogen will be flowing form the top of the bed to the bottom. Do I have to select each spherical particle form the top layer as a part of manual selection for the inlet and similarly for the outlet. But this is not working out. Please help me.

Thanks
