Surface Growth on Lagrangian Particle contact

Robson_Aguiar · December 18, 2020, 16:47

Hi Everyone.

I am running some tests and letting lgrangian particles go through a pipeline however I would like to check if there is any material explaining about surface growth as lagrangian particles touch the wall.

I would like to create this kind of deformation as the contact happens but I do have no clue how to start.

Thanks in advance.

you should be able able to do this using the mesh morpher using displacements driven by the impact forces of the L2P particles. i say 'should' because there are less post field functions available for L2P than there are for DEM particles. you can read about morphing here: Simulating Physics > Space, Time, and Motion > Modeling Motion > Working with Morphing

another approach which i have seen used very successfully is the erosion model when combined with the morpher to show for example wear in a pipe due to abrasive particles - see Simulating Physics > Multiphase Flow > Using the Multiphase Segregated Flow Model > Modeling Particulate Flows > Erosion Model Reference
