Fluid-Structure Interaction Particle blockage

Please login with a confirmed email address before reporting spam

Hello! Have a nice day!
I am solving one problem in COMSOL Multiphysics Fluid-Structure Interaction model (FSI) at the moment. I need to take results in which particles must blockage porous media. I solved this task until halfway after then appeared errors: Condition for remeshing still fulfilled after remeshing. When one particle close porous throat this particle automatically remeshes until minimum quality after that mesh quality reaches minimum and run time stops. And thus another particles could not reach other porous throats. I put below some movies about particle tracing.
My email address: dansho.91@mail.ru

My questions:
1) How can I stop meshing a particle which is blocked pore throat and for other particles let continue meshing?
2) Is it possible to change domain property when this domain collides with another domain (For example: When particle collides with wall change particle's domain to fixed constraint)?
3) Can I release geometry by time from FSI model and automatically give material property (like Particle
tracing model there this parameter is available)?
4) Can I give boundary condition in FSI as Particle tracing model (bounce, stick, freeze etc)?
