Greetings friends,
I was wondering if it's possible to simulate the effect of jamming (blockage) in a screw conveyor due to non-compatible particle size distributions, too high feeding rate, too high friction among particles, etc...
Specifically, do the particles interact with the rotating impeller and can influence its rotation speed ? Or cause the rotational operation to stop ?

Hi David,
Hi David,
This is normaly not possible bc. the mesh rotates with a constant velocity so the motor has unlimented power.
BUT we have developed an interface between LIGGGHTS and OpenModelica (a language to model multi body systems), so we can make a simple motor with a realistic power-curve and than couple it with mesh/surface/stress to get the torque at the motor-shaft.
For an example look at this video:

The Wheelloader is stopped by the particles while the tires are rotating (bc. of less friction between tire and ground in the MKS Model)
Best,
Christian.
