Overlapping generations model

Hi i am beginner at Dynare. I am trying to analyze the multi-periods overlapping generations model through dynare, but I am in trouble because I could not get steady state. Can you give any advice?
Also I want to find examples for multi periods OLG model. I can only find just 2-periods ones. Please help. Thank you.

Your model features growth:

G(+1) = (1+n) * G;

L(+1) = (1+n) * L;

Obviously no steady state exists here. You need to detrend the model.
