I am trying to create a system which has sensors which attract and trap particles as they come close. Is there anyone out there that would know how to go about doing this? I am trying to make some kind of UDF to do this but have not had any luck so far. If anyone can give me any help with creating an attractive force it would be appreciated.

first evaluate a mathematical relation for attractive force caused by the sensor as a function of space and then use that in DEFINE_DPM_BODY_FORCE macro.

I tried to make a UDF for this but it did not seem to work for me. If there are any other suggestions or examples of this you can give me it would be greatly appreciated.
