You have not added PERFORM ANALYSIS command. You need to add that.
There are warning for wind load generation. There are few instances where the WIND load command is not associated with a specific exposed face. So, the program has to scan through the whole structure to find one. When it runs into what it perceives as intersecting members without a common node at the intersection point, these messages are displayed.
I would suggest you to provide the coordinates of the Exposed area with some tolerance as X range ,Y range and Z range in the wind load case definition ,so that the concerned nodes are covered by the ranges . This helps the program to identify the proper exposed area for wind load. Or you can associate them with a member list or a group name in each case, and the message will disappear.
