Good afternoon to all. I want to write an equation with a division. My problem is that trnsys report me an error saying that the equation has a division by zero. I put a condition (multiplying for an _expression_) that avoid the division by zero but it doesn’t work. Someone could help me? Thanks to all Inviato da Posta per Windows 10 Da: David BRADLEY Wirich, There are two basic Types that can be used to read weather data. Type15 is designed to read files that have a standard format (such as TMY2 or TMY3). Part of the standard format is a 1-hour timestep. If you modify a standard format weather file to have a different time step then it can no longer be read by Type15. Type9 can be used to read general weather data files. However, it does not have the solar radiation processing algorithms built into it as Type15 does. You'll need to use Type16 to process the results that are read by Type9. kind regards, David On 04/29/2016 09:20, freppelw@noirot.fr wrote: > Hi everyone, > > As you know, the weather file for TRNSYS (TM2) is built with a 1 hour > time step. > > My question is: If I modify the weather file so that I have a time > step of 1 minute, would TRNSYS be able to execute the simulation?
