Hello.

I’m trying to co-simulate Energyplus with Matlab and Simulink in BCVTB environment. I tried to test examples but the simulink examples “ePlus85Simulink-simple” do not work.

The following error shows: “IOException while reading from server.”

I was able to successfully run the ePlus85-schedule and matlab-room examples.

I tried using Matlab r2015b and r2019b, and both failed by same error.

Any advice is greatly appreciated!

Here are my working environment:

Windows 10 Home ed

BCVTB 1.6.0

Java 8 update 241 (build 1.8.0_241-b07)

Matlab r2015b/r2019b

Energyplus 9.2.0

Thank you.

Do you get any error message from Matlab/Simulink? It is suprising that the Matlab examples run but the Simulink examples do not...

Are you using a Matlab shared network license? If yes, it may be that because you are trying to run both, Matlab and Simulink, that there may be some license issues...

Yes I used academic network license.

OK I'll try another way. Thanks!

Hi, Thierry, Thanks for your reply. I am still a little confused. Does it mean that we can not run MATLAB and SIMULINK the same time, while using BCVTB? We use Academic license but the license allows us to run both programs at the same time. We have been using BCVTB for two of our research projects and really would like to continue to use it. Any help is appreciated?

You should be able to run both at the same time. I was thinking about the case of a network license with single seat but I actually see that you can' t even run the Simulink example. So the problem is not the license.

In your screenshot you can click to display the stack Trace. Could you please do that and send the output of it?

Hi Thierry. Thank you

I tried another java version, but same error occred.

I ran the example "ePlus85Simulink-simple" chaning the socket time to 100000, and the following is output of stack trace.

thanks

Hi, I am also experiencing the same problem. May I know if you have any solution to this?

Hi. I also tried the simulink-room example using Matlab 2022a. I tried to run the blocks in simulink and got the error as seen from the picture. I suppose the blocks were created using an obsolete version of matlab and the latest version no longer supports it.

I don't have the latest version of Simulink, but we had similar incompatibility problems in the past when Mathworks chained its binary format.

I suggest you try to recompile as described at https://simulationresearch.lbl.gov/bcvtb/releases/latest/doc/manual/tit-buiManSys.xhtml to see if this helps.

Dear Mr. Wetter,

Thank you for your response. I tried to recompile it but it threw the following error. I couldn't figure out what caused it. Could you please help me? Thank you.

Rezky

If you run the commands shown next to [exec] from a dos shell, you may see more information from matlab that helps you isolate and correct the issue.

All the best,

Michael

I haven't been able to locate the problem, unfortunately. However I've found a way to make the simulation work through matlab, instead of simulink. Thank you for your help, Mr. Wetter.

I have missing the same issue. And I tried the mentioned method. Unfortunately, it doesn't work. When I run the example simulink-room like Mr. Rezky, the same error message was got. Can you share the solutions? Thank you very much.

Unfortunately, I couldn't find the solution for simulink either. It seems like the mewcx64 file (if I'm not mistaken) which comes with the BCVTB library is not compatible with the newer version of simulink. I tried to recompile it but it didn't solve anything. I gave up on using simulink and tried to co-simulate using matlab instead

Dear Mr. Rezky, Thank you for you warm reply. I will stop looking for a solution to this problem temporarily.
