COMSOL if statement

I am trying to plot an arrow surface plot where the resulting arrows depend on where they are located in the geometry.
if (distance from xo,yo to x,y is less than r)/squareroot(absolute(x-xo)^2 + absolute(y-yo)^2) < r
then (the x component of the arrow is equal to dh/dx * -K2)
else (the x component of the arrow is equal to dh/dx * -K1)
(The dependent variable in my PDE is h)
How do I formulate this in COMSOL?
Another way I thought of solving this issue was defining some data set within a circle. But I also can't figure out how to do this?
