Hello guys,

#includeEtc "caseDicts/setConstraintTypes"

what circumstance do we use this?

[christoph45]

have you found out yet?

I'm doing the "simpleRotor" tutorial for overset meshes of OF1706.

all files in /0 have this entry in it:

#includeEtc "caseDicts/setConstraintTypes"

In Paraview I get the error:
0/U: Unsupported directive includeEtc

includeEtc is an include command for the folder OpenFOAM/OpenFOAM-v1706/etc (well it depends on your OF Version)
In Your case

#includeEtc "caseDicts/setConstraintTypes"

includes OpenFOAM/OpenFOAM-v1706/etc/caseDicts/setConstraintTypes which is a file with the following content:

cyclic
{
    type  cyclic;
}

cyclicAMI
{
    type  cyclicAMI;
}

cyclicACMI
{
    type  cyclicACMI;
    value $internalField;
}

cyclicSlip
{
    type  cyclicSlip;
}

empty
{
    type  empty;
}

nonuniformTransformCyclic
{
    type  nonuniformTransformCyclic;
}

processor
{
    type  processor;
    value $internalField;
}

processorCyclic
{
    type  processorCyclic;
    value $internalField;
}

symmetryPlane
{
    type  symmetryPlane;
}

symmetry
{
    type  symmetry;
}

wedge
{
    type  wedge;
}

overset
{
    type  overset;
}

You can copy this file into your boundary condition instead. This gives all boundaries with the name empty the type empty. If your boundary is named frontAndBack for example this won't do nothing. Paraview will complain since it does not know this command. This can simply be ignored, or you copy the needed ones into your file. It is simply used to shorten the boundary files a bit.
