Hi,

This is a basic tube with a square that heats the air in the tube.

After many attempts I asked the solution to plot the velocity while calculating.

To my surprise the speeds just explodes with 5W of heat flux!!!
At some point the flow of air even reverses.

Can somebody please look at this issues.

Thanks in advance!

Christian
