Error at try to run simulink model for second time

I am trying to run a loop with a simulink model in it. The first time it works fine but for the second time it always show this error : Could not open file C:\Users\~\AppData\Local\Temp\tpb8ede6ea_5590_4b49_86c5_5f94a36f1967rp948\w\slprj\slprj_sfprj\~\sfun\src\lib_Functions_sfun.mol. No such file or directory. for some reason it erases those temporary files after the first run and then expects them to be there for the second run. I already try to use clear all, in order to avoid any connection between the different runs but it always show the same error. The only solution I have found is to close and open Matlab again. That is not a real solution.

Jorge,

I came across this same issue in one of my models. I am running Matlab R2017b in accelerator mode. It turned out that I had a set of generated code on my path that I didn't expect that contained the same model reference as the model I was trying to run. To describe my setup a little bit, maybe we have something in common that causes this error:

• The problem model is contained in a model reference
• The problem model has many library links to various different libraries
• The problem model_sfun.mol is a linked library within my model reference and contains custom C code

So basically my model hierarchy was as such -- I was trying to run the 'Top Level' model:

Top level -> Library Link -> Model Reference -> Library Link -> C code call
             ^Code was previously generated at this level and was contained on my path

Deleting the code from this previous generation fixed my issue and allowed back-to-back runs. I have other model references that would have had the same issues but didn't complain though so I'm not sure exactly why this one reference didn't work.

Hopefully this helps
