This is a repost, because the original one got lost during the disk failures.

Can somebody please tell me if the following tolerances are read absolute (which dimension) or relative (to which reference):
/OpenFOAM1.x.x/.OpenFOAM1.x.x/controlDict/
slidingPointMergeTol
slidingEdgeMergeTol
slidingIntegralAdjTol
slidingEdgeMasterCatchFraction
slidingEdgeEndCutoffTol
slidingEdgeCoPlanarTol

Hrv already answered this question, but I'm sorry I cant repeat the answer exactly. Therefore I wont post so nobody gets confusedhttp://www.cfd-online.com/OpenFOAM_D...part/happy.gif

Maybe you could post the answer another time, Professor Jasak?

The reason I've been asking this is because I'm struggling with sliding interfaces. Therefore, I wanted to know a little better what I'm doing.

The problem is that some points are moved in such way that several faces are degenerated to lines and points. (some of them also seems reversed)

Attached are some pictures to make things clear:
master(red)&slave(green) at time 0
masterslider at time 0
tangential cut through sliding interface at time 0
broken case
masterslider broken
tangential cut through broken sliding interface

Hopefully somebody can help me on this case.

Why do you need to know - they are there to be changed only by the
experts (me!). The code should work without fiddling with the
tolerances for all but pathological cases.

For reference, all the tolerances are relative and calculated based on
the local length of the relevant object in the action. Also, there are
inter-dependencies between the tolerances which should not be
violated.

As I said, best left to the experts. If you wish to know how, have a
look at the projection source code:

slidingInterfaceProjectPoints.C
