Hello,

In Geometry creating stage, I didn't spacify some of faces. I created a packed bed of spheres and then in order to specify domain, I created a box around the packed bed. Now in CFD modelling, I want to specify 4 sides of the packed bed as wall (symmetry), as 2 of 4 walls can be seen in the figure. But in CFX, there is no option to specify and name walls. Do I have to return to the first stage and name all faces? or in this current stage I can do it?



Many thanks in advance.
