Error in type 56: minimum desired mass flow rate
Hi all,I'm also working with Trnsys 17, and I have the same error, I tried to find a solution for this error, but unfortunately I can't find it until now.
Best Reagrds,

Subject: [TRNSYS-users] Error in type 56: minimum desired mass flow rateThanks!Has anyone ever had this problem?I have tried everything, from increasing the desired flow rate, autosegmentating the surface to changing the type of wall without active layer or deleting the surface, but the error persists and I don't know what more to do.Hi,I'm working with Trnsys 17 and I haven't had this kind of error until now:
"Specific fluid mass flow of active layer in surface 22 below minimum value of 3.89 kg/m2h Please, increase the minimum mass flow rate or use the autosegmentation feature of TRNBuild for subdividing the surface."

Subject: [TRNSYS-users] type 33 errorHello
Using type 33c (psychrometric) for fan outlet air, I'm getting following error. I checked the inputs, there are just 2 inputs (temperature and humidity ratio) and pressure is 1 atmosphere. how to solve it ?Thank you------------------------------------------------------------ ------------------------------ ------------------------------ -------------------------- amirrezaheidarymaster student of energy systems EngineeringSharif university of technologyTehran-IranE-mail address:P Save a tree...

María,
This sounds like one that should be sent to your distributor for some assistance. If you aren't sure who to contact, please let me know and I can help find the right hotline based on your license.
best,
David

Subject: [TRNSYS-users] HELPHello everybody,I come today to ask you a particular case.I have an output temperature of a model that I want to use to influence another input. Let me explain, depending on the difference in temperature at the outlet (delta T), I want to adjust my inlet temperature so that the inlet temperature follows the variation (T2-T1). Ie the new input temperature will be equal to the input temperature I have + the output temperature variation. (Tin (new) = Tin + (All 2 - All 2)). But I do not know how to have the temperature difference on TRNSYS.I hope it's clear enough, I know it's not obvious.Thank you in advance.Best regards.ᐧ
