Overview

This API allows you to simulate any kind of particle expansion/growth/swelling and shrinkage in EDEM. There is also an example attached that shows the usage of the API.

Usage/Installation Instructions

  1. Extract the zip file attached. Copy the 'ParticleGrowthCycle.dll' and 'ParticleGrowthCycleInput.txt' from the 'example' folder to the directory of your EDEM simulation.
  2. Add the plugin model in 'Particle Body Force' of the Physics section.
  3. You must enter three different values - expansion/shrinkage rate, final scale and start time of the expansion/shrinkage, in the preference file (ParticleGrowthCycleInput.txt).
    Use negative values for shrinkage. Higher the rate, faster the process.
  4. You can have multiple lines of the values to indicate different cycles of swelling and shrinkage in your simulation. Note that you can have a maximum of 40 rows only.

All the particles in your simulation will grow/shrink at the rate you specify in the preference file.

Post-Requisite

If you are interested in just the expansion/shrinkage once, and not necessarily the cycle of expansion/shrinkage, you can refer to this API: https://community.altair.com/community/en/edem-api-particle-body-force-particle-growth?id=kb_article&sysparm_article=KB0122138
You will also be able to add different rates for different particles using the linked API.
