[TRNSYS-users] Calling EES --> Error: Clipboard data contains characters instead of numbers

[Christopher McNevin via TRNSYS-users]

Hi Karolina,


I have had the same problem in the past. For me it was because EES kept old data in the clipboard from previous calls. You can see this by pressing paste in Notepad after running the EES program, it will contain 2 lines of data instead of one. To fix this all you have to do is add the /c command to the Export directive in your EES program which clears the clipboard before pasting the data to it. The manual and example for EES to TRNSYS doesn't mention this is required but I found it works after doing this.


I like to add the /d command to the export directive as well so it outputs the data in the same format as in the solutions window as this might also be part of the problem.


Hope this helps,

Subject: [TRNSYS-users] Calling EES --> Error: Clipboard data contains characters instead of numbers

Dear TRNSYS-users,

I encountered a problem that was already discussed twice on the forum
(2016 and 2014), but did not find any solution within the messages.

In the past (since 2014), I  was taking advantage of a very useful
option of TRNSYS to couple the simulation with EES code and have never
had a problem of the nature I am going to describe.

This month, I was trying to use the Calling EES type 66 with the newest
version of EES V10.268, but was not able because an error occured saying:

"Clipboard data contains characters instead of numbers"

I am sure I am using "." as a decimal point and "," is the thousands
separator.

I promptly came back to the Example project "Calling EES" with
compressor.ees file to check if I can run this one - It is always a good
reference case.

Unfortunately - I was not able to. I checked and: the input data are
loaded to EES, the calculations in EES are performed, but the command
"$Export 'CLIPBOARD' out1, out2, out3, out4, out5, out6" somehow
transforms numbers into characters which cannot be accepted by TRNSYS
Simulation Studio anymore.

The problem could disapppear, if I wanted to store the results in an
external file, e.g. if I put "$Export 'C:\...\compressor.txt' out1,
out2, out3, out4, out5, out6" - the results will be saved in the created
compressor.txt file. Nevertheless, it is not the best solution, since
sometimes I would like to perform further simulations in TRNSYS on
EES-outputs...

Do you have any hint? Maybe changing the Export command type could help...

Thank you in advance for support :)

My regards
