<DIV style="RIGHT: auto"><SPAN style="RIGHT: auto">The second question is that I've observed when I used weather external file by using Type 9a and radiation process Type 16i with the other components of thermosyphon system to complete the system and the optimisation componet TrnOpt there is an error although when I run it without the optimisation componet it's working fine. the error I get is:</SPAN></DIV>
