Subject: [TRNSYS-users] Modifying connection line properties ?
Dear users,
is there a way to modify the properties (e.g. change color or weight) of multiple connection lines between components at the same time. It takes a lot of time to change line properties one at a time.
best regards,
Santeri Siren

Dear Santeri,
right-click on a connection with the style you wish to copy and choose and choose "copy style". Them, you can copy this to another line just right-clicking on it and selecting "apply style"

Subject: Re: [TRNSYS-users] Fwd: Converging error
Dear 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 surfaces
1.) You didn’t connect TSGRD such that it is set 0 => If you have no information set it Tamb
2.) 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.

Betreff: Fwd: Converging error
Dear 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] Converging errorWang,
This problem may occur from incorrect ambient condition settings:
Please check the following inputs of Type 56
1- TAMB
2- RELHUMAMB
3- TSKY
4- TSGRD
In addition make sure that in the BUI file the surface
- outside emissitive is ≤ 1
- outside convective heat transfer coefficient ist set to reasonable value
If the error presits, we need the complete project to give further advice.

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,
Matt Duffy

Dear All,
I try to simulate dwelling with natural ventilation. I set some algorithm for window opening and ideal heating for colder part of year for each zone with set temperature depending on time of day.
When I run my yearly simulation it stop in one moment and TRNEXE is frozen... There is even no error! Then I can only turn off TRNEXE.
Only think what appear (many times) in .lst file is
Notice: More than 6 iterations for internal regulation HEATING/COOLING.
I will be grateful for any advice!
I enclose .lst file.

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 the
integrated 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.

Marion

Dear 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.
