Re: [TRNSYS-users] Type 155 can't load when running 'Calling MATLAB' Example (Keelia LaFreniere)

Dear Keelia,

Apart from what you listed and David suggested, I would recommend to run the command 'regmatlabserver' in your matlab command window. This registers Matlab as comserver. This was my reason why it did work for me last week and I found this out from the Archive of the user forum.

With Regards

Muthu

Subject: Re: [TRNSYS-users] Type 840 Error
Dear Behzad shahzamanian sichani,

as far as I can see you are using a model for a PCM storage. If this is so (there is not a lot of information in your mail) than it is a non-standard type developed at our institute.
If you still have problems, please send me an email.

Best regards,
Hermann Schranzhofer.

Dear Users,

I want to use type 840(pcm storage) in trnsys 17 but it gives an error:
"unable to find fluid data file". What exactly i should do? Thank you in advance and look forward to hear from you.

Best regards,

Subject: [TRNSYS-users] CO2 based demand controlled ventilation with Trnflow
Dear Trnsys users,

I’v modelled a multi-zone none-residential building in TRNbuild with HVAC system which is modeled separately in Trnsys.
In order to implement a CO2 based demand controlled ventilation, I need to insert airflow between different zones as well as calculation of CO2 concentration for each zone which can be then connected to the controller of HVAC system.
I have 2 questions:air
1.       Regarding airflow between zones/ air coupling, I applied air coupling function in Trnbuild but the zone-temperatures changed a lot and they somehow got overheated although the air flow rates were given according to the technical documents, how can I solve this problem ?
2.       Regarding CO2 based DCV Since I have no experience with Trnflow, I would like to know if anybody has any idea about it.

Thanks in advance !

Best Regards,
Hamidreza Esfehani

Subject: [TRNSYS-users] Type 155 can't load when running 'Calling MATLAB' Example

Hello everyone,

I am trying to use Type 155 in my simulation, but I can't even get the calling Matlab example running. I encounter the following error:

I am running a x64 system with Windows 10, Matlab R2017b, and 64bit TRNSYS18.

'Your input file uses Type 155 (Calling Matlab). "Type155.dll' was found but could not be loaded. Please make sure that a supported version of Matlan is installed and that Matlab's "bin\win64" (or "bin\win32" if you are using the 32-bit version) folder is on Windows' search path.'

I have made sure the EXE folder in TRNSYS18 contains the Type155.dll version corresponding to my Matlab release. I have also added the folder for Matlab's "bin\win64" to my path environment variable.

I wiped my hard drive and reinstalled everything from scratch. I continue to encounter this issue.

Does anyone have any suggestions? I'd appreciate the help.

Kind regards,

Keelia

Keelia,

It certainly sounds as though you have gotten all the key things checked. The only three other items might be to:

1. make sure that there are not more than one reference to Matlab installations in the path environment variable

2. make sure that both your user account and the SYSTEM user account (built in to Windows) both have full read/write access to the Trnsys and Matlab directories.

3. make sure that neither Trnsys nor Matlab is installed in the .\Program Files\ directory. That directory has a lot of read/write restrictions that pertain even to admin user accounts

kind regards,

David
