Dear All,
Why my calculation for dielectric tensor suddenly stopped at this point ans gave me a completed job sign?

My guess is that it ran out of memory. The automatically detected 3x3x3 repetition is perhaps applied to an already large unit cell, creating a very large system. If so, and if appropriate, set the repetitions manually to something smaller, at least for testing.
