Hi all,
i’ve been trying to solve my model with an external SS file, also made a smaller version of my model run. But I cannot figure out how to make the complete version working, there is always a
little residual left, whatever I tried out.
Would be grateful if someone could give me an advice 
You did not provide all the files needed to run the code. The optimv8b is missing.
Sorry, this is equivalent to optim. Here is the revised code. Many thanks for your help!
Console calls first the optim file and then the dsge file.
You can check the exitflag from your optimizer. It shows that the solver did not solve the equation system. I would recommend approaching this analytically, not by brute force.
