I'm trying to do a study to see if the sheet metal used for a foldable Braai/grill will buckle due to the heat generated from the fire, I got these plans from Grabcad. I've been trying this and am failing miserably. I get it done fine with just the " Steady State Heat transfer", but with buckling the solve button stays grayed out and it won't solve. No luck with tutorials either. I have seen one with convection, but it doesn't help me.
