Thanks a lot David,Indeed, The type 56 was before the shading component. After checking component order in the input file and arranging them in the appropriate order, the simulation runs without problem.
Thanks a lot for your help. Best regards, Adrien David Bradley a écrit :
Adrien,Check the order of your components. If Type56 appears in the input file before the shading component then it gets called first and sometimes gets an incidence angle from the previous time step before it gets the revised incidence angle from the current time step.Cheers, David At 02:24 7/13/2007, Adrien JEZEQUEL wrote:Dear David,Thanks a lot for your answer and your explanation which were really helpful to adapt the *.msk file.But I encounter another problem concerning beam radiation on facing East : warning messages appear and block the simulation running (when the maximum number of warnings allowed exceeds of course). I am not sure that increasing the maximum of allowed warnings is the right way. So I am searching some way to fix these warnings but without success.The warning message is written below. It concerns beam radiation on East surface orientation with Type 56: /"Beam radiation greater than 0 occured for an incident angle of 100.48 greater then 90° for orientation 11. Beam radiation has been set to 0."/ This message appears for every surface which have east orientation at different time step.If anyone have an idea concerning that problem, he's welcome. Thanks in advance for your answers. King regards, Adrien David Bradley a écrit :Adrien,The first column in the *.msk file is the angle formed between the horizontal and an imaginary line drawn between the center point of the shaded surface and the top of the obstruction. If you enter an angle of 0° that means that the obstruction has a height of 0 in that direction and that the surface would be unshaded from sunlight coming from that direction. If you enter a value of 90° that means that the obstruction has an infinite height in that direction and that the surface would always be shaded from sunlight coming from that direction. 0° = no shading, 90° = complete shading (for that surface angle direction)Cheers, David At 11:17 7/12/2007, Adrien JEZEQUEL wrote:Dear TRNSYS users, I'd like to model shading masks, caused by neighbour buildings. To do that, I am using Type 68 with "mask file". I understand how to use it and to connect it to others components. But I am not sure to really understand how the first column of the file is taken into account by TRNSYS. If I put an angle between 0 and 90 °, it means that there is a solarshading isn't it? But if I write 0 or 90°, what does it mean? How thesevalues are interpreted by the component : Total shading? No Shading? Thanks in advance for your help.
