y+ sampling on arc
 

Hi,

I'm trying to get y+ values on an arc.

arc 10 18 (204.5 36.63 0) is my BlockMesh define (here is values are cm)

weir_leftc
{
type uniform;
axis y;
start ( 2.2 0.31 0.005 );
end ( 2.265 0.375 0.005 );
nPoints 100;
}

This is my sampling data (here is values are m)

when I do sampling I got only 1 value for arc although I need 100 values. Do you have a solution for this? Can I give another type or 2 axis for sampling?
