<DIV>Hi Fabien,<BR><BR>You do not need to use Type34 in combination with Type67. Type 67 was <BR>created to avoid the problem that you found in the mailing list: having <BR>to use two instances of Type 68. My answer to Amelie was before Type67 <BR>was available.<BR>Best regards,<BR><BR>Diego<BR><BR><BR>Fabien Morice wrote:<BR>> Dear TRNSYS users, I have some questions for you :<BR>> <BR>> 1°) I try to use the type 67 with the type 56a (Multizone Building).<BR>> But, it seems to me that I *_must_* used the type 34 in <BR>> complement.<BR>> [Output 11 of type 34 (Fraction of solar shading) ---> Input <BR>> of type 56a (created by me to used in Input of External Shading Factor)]<BR>> because the type 67 gives me 2 outputs (among 11)
:<BR>> [Output 7 of type 67 (Fraction of beam visible on horizontal <BR>> for mask) ---> ?<BR>> [Output 9 of type 67 (Fraction of diffuse visible on <BR>> horizontal for mask) ---> ?<BR>> that I don't know used with the type 56a directly. <BR>> 2°) I have read the files of the forum and I try the solution <BR>> proposed by Diego (Wed Oct 26 2005) to Amelie Mariller<BR>> who recommend to use two type 68 (one horizontal and one <BR>> vertical) with each type 34.<BR>> So, I have created two files in ".dat" :<BR>> the first with a slope of 0°<BR>> and the second with a slope of
90°.<BR>> The two files dividing the same others informations.<BR>> But I have the message : Error "Unable to read mask file, <BR>> please check file syntax and format." when I launch the calculs.<BR>> <BR>> 3°) So, I use only one type 68 with one type 34 :<BR>> <BR>> [Output 3 of type 67 Shaded beam radiation for surface ---> <BR>> Input 5 of type 34 (Beam radiation on surface)]<BR>> [Output 10 of type 67 Shaded diffuse radiation on horizontal <BR>> for mask ---> Input 4 of type 34 (Horizontal diffuse radiation)]<BR>> [Output 11 of type 67 Shaded total radiation on horizontal for <BR>> mask ---> Input 3 of type

simulation, I have controlled the five View factor <BR>> (Outputs 6,7,8,9,10 of type 34) by Online plotter (type 65d)<BR>> and I'm surprise because the sum is not equal to 1 !<BR>> But if I change : <BR>> Parameter 1 of type 34 Upstream component mode = 0 and not 1<BR>> the sum is correct.<BR>> <BR>> * Anyone knows what I should do?
