<BODY bgcolor='#ffffff'><font size="2"><font size="2"><font size="2"><font size="3"><span style="color: rgb(0, 0, 0);"><span style="font-family: Arial;">Hi everybody,<br>i have 2 warning messages in TRNSYS16 that i dont succeed in fixing them.<br><br>The first one refers to output printers Type25a : <br>the
printer has rounded the reset time to an even number of steps.-Please
check to make sure that it doesnt adversly affect your simulation
results.<br><br>I think it is because i have put my steptime (in control
cards) to 10min that is to say 0.1667h. I havent this message when i
put back 1h as a timestep.<br>I think the cause in printer is the 1st
parameter set to STEP with unit=hr. Could you tell me what STEP
represents? I was thinking this value to be the steptime in control
cards.<br><br>The second message refers to irradiation :<br>"the direct
beam is greater than the maximum allowed for this timestep. The
extraterrestrial radiation has been used for this time step."<br><br>this message refers to unit 60 which is type16c (radiation processors).<br>i
read my total horizontal radiation from datareader (type 9c). the
maximum value in my file for radiation is 975W/m² (3510kJ/hr.m²). I use
a multiplication factor in data reader for radiation (3.6) in order to
switch to kJ/hr.m² and i send the output to radiation processor which
solar constant parameter is seto to 4920kJ/hr.m².<br><br>Maybe the
problem is about units of the input from data reader. I have tried to
send the output of datareader to unit conversion routine (type57). I put
parameter 1=17 parameter 2 and 3=1.<br><br>Thank you for reading. I hope i have put enough details in order you can understand and help me.<br></span></span></font></font></font><br><div style="background-color: white;"><span style="font-size: 11pt; line-height: 150%; font-family: "Times New Roman";"><font style="color: rgb(65, 105, 225);" size="4"><span style="font-weight: bold; font-family: Arial;"><span style="color: rgb(100, 149, 237);"></span></span></font></span><span style="font-size: 11pt; line-height: 150%; font-family: "Times New Roman";"><font style="color: rgb(65, 105, 225);" size="4"><span style="font-weight: bold; font-family: Arial;"><span style="color: rgb(100, 149, 237);"><font size="5"><br></font></span></span></font></span></div></BODY>
