Particle with two halfspace

Submitted by JohLoh on Mon, 06/26/2017 - 16:56

Hi All,

is there an easy way to implement a spherical particle, which has a high young's modulus on one halfspace and a small on the other halfspace (such as a Janus particle)? For example, could I define a point on the particle's surface, which follows the particle's streamline and the angular velocity?

Thanks for help.

Easy no, but possible, sure :)

It would certainly mean to do some coding. So you would want to code a fix that, after the integration, updates the position of the tracking point. This tracking point needs to be used in all your contact models to decide which Young's modulus it would take.

Best,

Thanks for your answer Arno. Is the spot of the deformation stored in the history of the multicontact model and acts like a tracking point? Than I could chose this multicontact model as basis for this task?
