Subject: [TRNSYS-users] Weather Data Reader Type15Dear user,I'm trying to extract some weather data from TRNSYS -16 after reading and processing EPW file using Pereze model (time step 1 hr). I have noticed that this TYPE interpolates the variables including the air temperature. Is there a way to extract the data without interpolation using this type or others?regards,Saleh ALSaadi

Subject: Re: [TRNSYS-users] Fwd: Converging error
Dear Wang,1) I use TRNSYS 16, there is no TSGRD in TYPE 56.
Ok. Please always include the TRNSYS release number .2) The height over sea level of Default is 0 m I used.
Default values NEED to be adapted to your data!3) You are right. I tried to use *.tm2 weather data, this Error disappeared!As I mentioned previous, there must be an error in your data file. Link the outputs to the online/printer for checking4) Yes, The data reader Type 9 is placed after the building now for my simulation.,For a successive method all input data types should be placed at the beginning.Check the component order and rearrange it.MarionDipl.-Ing.

Betreff: Re: Fwd: Converging errorDear Marion,
Many thanks for your patient reply!
1) I use TRNSYS 16, there is no TSGRD in TYPE 56.
2) The height over sea level of Default is 0 m I used.
3) You are right. I tried to use *.tm2 weather data, this Error disappeared! But my Userdefined weather data is TRN/TRY weather data. Why does it result in aforementioned Errors (Converging error by my past emails)?
If I must use our own TRN/TRY weather data, how to avoid this Converging error?
4) Yes, The data reader Type 9 is placed after the building now for my simulation., Do you mean Type 9 should be placed before the Building Type 56? Is Better?
Many thanks in advance!

wang2012/10/10 hotline <hotline@transsolar.com>Dear Wang,there are several issues within your simulation concerning the outside longwave exchange of external surfaces1.) You didn’t connect TSGRD such that it is set 0 => If you have no information set it Tamb2.) For Sky temperature calculation with Type 69, you forgot to enter the height above sea level.3.) You read the ambient temperature and the relative air humditiy from a userdefined file by type 9
instead of using the data from the weather file.
This file wasn’t attached, but it might be an error source especially when interpolating incorrect data.
For testing, please use the ambient temperature and rel. humidity from the assigned weather file throughout your simulation.
Please check your userdefined data and the outputs of Type 9 WITHOUT connecting them to TYPE 56.4.) In addition, please check the component order. The data reader Type 9 is placed after the building.Marion

Betreff: Fwd: Converging errorDear Marion and TRNSYS Users,
Thanks for your reply!
I checked all you mentioned, I can't find any special/abnormal settings. Furthermore, it runs well when the time step is 1 hour. For other steps e.g. 0.1 h, 0.2 h or 0.5 h, it appears that ERROR.
Please help me have a look at the attached project if you are free.
Many thanks in advance!

Subject: Re: [TRNSYS-users] problem with iterations??Karol,I noticed from your listing (*.lst) file that your working directory is located on your computer's desktop directory. This is not recommended due to the potential issues with the Windows OS system and write privleges. I would first try changing your working directory to the ".\MyProjects" directory or in a folder right on the "C:" drive. I am not certain that this is the issue with the TRNEXE, but if the problem persists, please contact your distributor, techsupport@tess-inc.com.Best regards,

Subject: Re: [TRNSYS-users] problem with iterations??Karol,In general the notice has nothing to do with a frozen TRNEXE.exe,it is just an information.The message indicates that the internal controller for turning on theintegrated heating/cooling has convergence problems and a deadband is applied to promote convergence.This may be the case at the moment of turning ON or OFF something.After 6 internal iterations a deadband is added to promote convergence.If the convergence isn’t reached after 12 iterations a warning is written to the lst/log file.Regards,MarionDipl.-Ing.

Betreff: [TRNSYS-users] Converging errorDear all,
I met a converging error when I changed simulation time step 1 hour into 0.1 hour or 0.2 hour or 0.01 hour as follows:
*** Fatal Error at time : 3972.000000
Generated by Unit : 56
Generated by Type : 56
Message : outside temperature of 2(external) wall in zone 1at time 3972.00 not converged!
Please tell me some possible solutions for that if you know. The attached is its Listing File.
Many thanks in advance!
