Dear Fellows,

For periodic you go to mesh/modify-zones/make-periodic. You need to have a rotational axis and two planes for rotational periodicity(and they should be similar in rotation), but in my case the left and right planes are not similar, in fact the right one is a bit translated in z (z is rot. axis) and start after some distance along z from the left plane, now if the left plane is rotated it would never be the same plane as the right one. I have now tried to model it as interface and then specify ROTATIONAL PERIODCI. But I dont know abt it much. Please let me know if any one has experience of that.
