Are you saying that CF only considers the increase in thickness for the calculation of the thermal resistance if Large Deflection is ON? I have it turned off right now, because I thought large deflection only applies to problems like fishing rods or diving boards.
My problem is more like the pic I inserted, I have a multilayered fire-resistant glass which consists of two glass panes (blue) and an intumescent layer in between (grey). Do you think turning on large deflection is the solution?
Thanks for your answer!
