Hello All
I am trying to model 2D natural convection with boussinesq density approximation. Attachment-1 shows the actual geometry I am trying to model along with the BCs & operating conditions I used. But when I try to run the solution it will not run and returns a message "floating point exception".
So I simplified the geometry and removed the bends and used a model as shown in attachment 2 with the same BCs and operating conditions and settings. But this one worked and no error message appeared.
Can anyone please help me and tell me what I am doing wrong with my actual geometry (geometry as shown in Attachment 1)
