Error in calculating Direct Solar Radiation

["Anil Misra" <anil_misra@xxxxxxxxxxxxxxxx>]

Dear TRNSYS users,
 
I received the following error during the hourly simulation of a small building having 6 orientations (N, E, S, W, NW, and SW). I tried to simulate the building for one complete year, but the error was displayed at the 4230 hour. the simulation proceeded all right from the beginning of the year. The deck uses two solar radiation processors (Type 16).
 
***** ERROR ***** UNIT 6 TYPE 56 MULTIZONE BUILDING
INCORRECT VALUE OF INCIDENCE ANGLE FOR DIRECT SOLAR RADIATION FOR 1. ORIENTATION ENCOUNTERED.
SIMULATION STOPPED.
 
I have checked all the inputs but could not figure out the error. Please help me by indicating where the error could possibly be located.
 
Thanks
