Hello,<\/p>\n

I am trying to heat a steel tube using impingement heating in an heater I modeled. As seen, the air flows in the -z direction to heat the tube that moves in the x direction at a constant speed. I am facing a problem in simulating the moving steel tube. I tried creating a dynamic mesh and using UDF but it is giving me:<\/p>\n

"Warning: incorrect cg motion UDF Tube on zone 8 (assuming no motion)"<\/p>\n

I tried then setting the governing equation for the steel tube and its wall bu the momentum tab is not appearing for the wall of the tube.<\/p>\n

Thankful for any help<\/p>\n
