No, you are wrong. OpenFoam is always running with a finite thickness in the empty direction, hence in your example, we are having 8 vertices. Look carefully on any case in paraFoam, and you should...

The example you have from the groovyBC only uses the pts() to find the upper and lower limit of the boundary. When assigning values, it is pos(), which is being used, therefore, the example is...

Hi Ehsan,

pos gives you the values in the face centres, whereas pts gives you the values in the vertices, hence they differ in size. This is probably the reason, why you only see that one of the...
