Re: [TRNSYS-users] TRNSYS-users Digest, Vol 126, Issue 33

Hi Ali,

In fact I faced similar problem while trying to connect the two software. As David said you must check which MATLAB version is supported in your TRNSYS version. If you are using trnsys 17, following the below steps must solve your problem:

Install MATLAB in your computer with specific MATLAB releases are supported, only the 32-bit versions are supported (to the best of my knowledge, the last supported version is R2012b).
Add MATLAB\bin\win32 folder directory to Windows search path.
Select a specific (Type 155.DLL) for your MATLAB version from (TRNSYS17\Exe\DLLs) folder.
Copy (Type 155.DLL) file to (TRNSYS17\Exe) folder.
From (MATLAB\extern\lib\win32\lcc) folder find and copy these files (libeng.lib, libmat.lib, libmex.lib and libmx.lib) to (TRNSYS17\SourceCode\Optional folder).
Copy (Type 155.DLL) file to (TRNSYS17\UserLib\ReleaseDLLs) folder.
Run MATLAB as an administrator.
Finally, write (regmatlabserver) command in MATLAB’s Command Window to register the desired MATLAB session as an automation server.

Hope you find these information useful,

Houssein.

Ali El-Nashar,
If you are using the most recent TRNSYS release (17.02.0004) then you will find Type155 DLLs for other versions of Matlab located in:

..\Trnsys17\Exe\DLLs\*.zip

Extract the files from the *.zip file corresponding to your version of Matlab and place them into the ..\trnsys17\Exe directory. You can either move or replace the existing files.

If you do not have the most recent release, it would probably be best to contact your distributor and obtain it.

Please be aware that the link between TRNSYS and Matlab only works with the 32-bit version of Matlab and that you need to make sure that you and the SYSTEM user both have full control level access to the computer.
kind regards,
David

Hello everybody,

I am trying to make a connection between TRNSYS 17 and MATLAB (version R2014a). When running the decks of the two “Calling Matlab” examples, I get this error message : unable to start the MATLAB engine. The version of MATLAB that I’m using apparently does not match Type155.dll installed in my computer. I’m looking for a copy of an updated version of Type155.dll that I can use. Could someone help me ?

Best regards

Ali El-Nashar
