In discrete phase model, is there any way to find the exact position at which particle is getting trapped? Thanks !

YES! What you do is enable step-by-step report type and it will tell you position velocity, etc.

Thank you very much for the response !! But step by step response will give the information about the particles present in the domain and not the particles which are trapped. I am interested in the position at which particles are getting trapped.

It is rare that you can find the solution to your problem at fluentusers, but in your case I think you can do it. At the fluentusers you can find a udf for counting wall hit, you can possible extend that to write the position. It is also described how to create a phs file which I think can solve your problem.
