Some variables are NaN after simulation

Dear Jpfeifer

I have got a strange problem in my mod file. After the simulation command, I can see the IRF graphs under the shocks I have set. But what puzzles me is that some important variables including Y didn’t appear on the IRF graphs. And all the moments, variance decompositions and the policy functions related to those variables are all NaN or 0.
Since the output variable Y is an essential variable in my work, I really need its response function and graph under monetary shock. It’s a pretty simple model and I did the log-linearization by hand before put it in Dynare.
Thank you for your time.
Have a nice day.

The problem has been solved. That’s because of my fault during the calculation of the steady states’ values. Thank you~
