MFIX---Force-displacement curve, uniaxial compression

[youminghao]

Hello，everyone！！！！

I want to implement it in mfix by compressing particle agglomerate using movable walls to obtain force-displacement curves. Can wall movement be achieved in mfix? Or is there any other method to help me obtain the force-displacement curve, similar to a uniaxial compression experiment.
Thank you very much！！

Hi @youminghao

Yes, moving walls are supported

The wall movement can be modified over time with a “keyframe” file, see the tutorials “conveyor”, “rotating drum”, “screwfeeder”, and “pulsating_fluid_bed_2d” for examples of this.
