Small shock but an explosive simulation

Perfect foresight simulations
1

Dear Professor Pfeifer,
I have a deterministic model which works well. However, the simulation does not work with one of the shocks when it goes beyond 0.02. That is quite low for the model. I was wondering if this reveals a problem in the model? and if not, how I could handle this explosive simulation? with increasing periods?!
Kind regards,
Leo

I would need to see the file.

Dear Professor jPfeifer,
Here is the file. the simulation works with eee or etfp shock 0.01 but not for example with 0.05 . Thank you for your help.
Kind regards,
Leo

In the solution process, there is one step that reaches Inf and afterwards, there is no solution. A workaround is to use a smaller shock and use the converged solution as a solution for the bigger shock:

shocks;
//capital quality
var eee;
periods 1;
values (0.04*1);
 
//tfp
var etfp;
periods 1;
values (0.05*0);
end;

perfect_foresight_setup(periods = 250);
perfect_foresight_solver;

oo_.exo_simul(M_.maximum_lag+1,strmatch('eee',M_.exo_names,'exact'))=0.05;
perfect_foresight_solver;

Thank you so much. Have a good day
