hi,

I have some issues regerding cyclic boundary condition. I am trying to match two cyclic boundary region, that lying parallel to each other in cartesian coordinate system. they donot have one 2 one correspondence. I am using arbitrary match option. it is giving error that offset must be opposite. what is the funda behind offset. please describe in detail

The offset is what must be added to one boundary to make it lie on top of the other.

So if Region 1 is at x=-0.5, and Region 2 is at x=1.5, the offset is xoff=2.0. If that doesn't work, try -2.0. I can never remember which way round it goes, and it doesn't matter, as long as it works, right?

hi,

Now the point is the offset to be specified in region1 or region2.ie in boundary region definition.

Both and opposite, as far as I understand it.
