I am reading the paper, and it states that points (5) are created along with measure (10). I created the measure thing with the commands below, but I do not understand it for points as the measure command generates it.

This are the line in the paper.

Also I want do the dynamic simulation and the fish code I have written is below.  
fish define wave  
wave = 0.5 \* (1.0 - math.sin(2_math.pi_block.mech.time.total/period))  
end  
fish set @period 0.5  
I want to use this Fish code in the below code. can anyone correct the code or tell me how to do dynamic analysis?

Your measurement spheres are fine. You can record some data through time by taking a history ([measure history](https://docs.itascacg.com/itasca900/pfc/pfcmodule/doc/manual/measure_manual/command_reference/cmd_measure/cmd_measure.history.html#measure.history) …). For the points, yopu can just take ball histories (e.g. [ball history](https://docs.itascacg.com/itasca900/pfc/pfcmodule/doc/manual/ball_manual/ball_commands/cmd_ball.history.html) velocity position …)

For the wave, you need to use mech.time.total, not block.mech.time.total and it should work. (not sure where you found this function?)
