Will there be a unique set of force distribution that will provide you with the desired R value? Have you checked the literature and found something on this algorithm? Your question seems to be very general and it is beyond the scope of ANSYS employees to provide you with a tailor made APDL code to do this. You could try finding/ creating such an algorithm and implementing it in APDL. If you have any issues running the code or implementing something specific we could help you with that.
