EDEM API Contact Model | Increase/decrease particle volume/radius?

MQ

Hello everyone,

Is there any way to change the particle volume/radius using API?

Particle replacement would not be an option, as I need them to gradually increase/decrease their size to simulate mass diffusion.

Thank you.

Best regards,

MQ

Hi MQ,

You can use the setScale function in the IParticleManager class. Once you update the scale, EDEM will automatically update the radius of the particle and all other related properties (like volume, mass, moment of inertia). Hope this helps you!

Hi MQ,

You can use the particle manager to getScale and setScale.

The particle replacement tutorial uses the particle manager function delete particles:

The spray coating API model uses the setScale function in CSprayPBF.cpp
