I have been working on simulation studies in power plant sector. I was able to successfully simulate the model using OMShell until Monday (12/07) but suddenly from 12/08, it is showing the above error in OMEdit. I Checked the .mo files from backup, it also shows same error message.

I am not a strong program decoder. The compilation process shows below error

STEAMPOWER.application.TURBINE_PLANT6B.c: In function 'STEAMPOWER_application_TURBINE_PLANT6B_eqFunction_4851':

Kindly let us know the best way to avoid/rectify this error.

@Manivannan, I'm not sure I understand exactly what changed. First of all, did you always use 1.16.1? Then, what changed between 12/07 and 12/08? You say that until 12/07 you were running your model in OMShell, but you got the error from 12/08 in OMEdit. Did you also try OMShell after 12/07, and if so, with which outcome?

Last, but not least, have you given a try with the 1.17.0 nightly build?

[Karim Adbdelhak]

If you want us to debug this we need to have a (minimal) example for a failing model. Do you use OMSimulator for FMI? Or do you just simulate it regularly?

If the model is proprietary you could encrypt it:
