Hello,

I am new to this forum and of course with the Star CCM tool. I am trying to solve a simple box natural ventilation problem. for this I created a 3D model in Rhino. I am following some online videos to set up the initial set up. I have created a wind tunnel and a room with some opening to check the meshing. but it causes an error that object is not fully enclosed. I have tried but couldn't resolve this issue. Any help/pointers in this regard would be highly appreciated.

thank you,
