I have a particle p1 generated at position x0 y0 z0

This particle is moving downward in a direction.

Now after the bond time t1 is reached, the particle diameter will change from d to 0.9d

And another particle p2 with diameter d will be generated at t1 position x0 y0 z0 and this will be moving downward

Now as 2*t1 is reached the diameter of particle p1 will become 0.8d

For particle p2 also as 3*t1 is reached the diameter will be 0.9d and for particle p1 the diameter will be 0.7d.

As the particles move downward there is bond between the particles

Similarly I will keep generating 5 particles of diameter d at position x0 y0 z0 as bond times t1, 2*t1 , 3*t1....5*t1 are reached. And as it moves downward I want to reduce the diameter of the particle.

This is a visual representation of what I am trying to achieve. Please tell me if it is possible to do in rocky

Hello,

yes, I think it is possible :)

You can use Particle Custom Inputs to add the particles at the desired time and position, and use the Transient Size Scale module for the size reduction. 

Download the modules package via the Ansys Customer Portal page and access the Rocky User Manual for more details on the Particle Custom Inputs.

Best regards,

Lucas

Thank you for suggesting this. I am able to decrease the size of the particles

But Now I am having trouble bonding the particles. 

(https://innovationspace.ansys.com/forum/forums/topic/bond-creation-between-particles-and-parameters-of-leblicq-model/)

I have asked the question about the bonds here(link above). It would be very helpful if you could please tell me how to do that.

Hello Lucas

I am able to use the transient size scale module and reduce the size but I am not able to understand which module should I use to define the bonds between the particles.

I have been looking at the SDK modules and am not sure which is the best fit for the bond. Can you please suggest a module that could potentially be used to creat the bonds between the particles.

As of now I am using custom fiber (with one particle) in the csv file and I am able to reduce the size. but I am not able to set up the bond.
