Hi,

I want to get integral of a variable till a point in the circle of radius r0, where this point would vary from 0 to r0. That means I want to get for all radius value till r0. With intop operator whole geometry is selected so, for interior points I tried to use if statement where for till the radius point where I intend to calculate is 1 and for the rest after that is 0. This gives the value at desired r. Now, since I want it for all r value from o to r0 what condition should I write in IF statement condition so that it takes the range from 0 to r0 with discrete step points defined by me.

Best
