CST 2014 simulation 99% aaaand...stopping.

Hello all,
I am starting to get badly anxious as I'm watching the progress bar in CST 2014 T solver. I reduced the accuracy expecting the simulation to end earlier, but transient analysis gets stuck in damn 99% and the countdown keeps rising.
Any hint why is this happening even to the lowest accuracy available -20dB? Do you know something I can do to end it properly?
I really thank you in advance!

Maybe tell us, what you are simulating, simulation setup (ports etc.)

LoL if it is a highly resonant structure it will take a long time before it stops! Try to introduce some lossy objects. Otherwise use F solver.
