cyclic match errors

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

Re: cyclic match errors

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?

Re: cyclic match errors

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.
