Hallo,
I want to insert particles with a mass rate of 1e-6kg/s to my computational domain. I tried to do so by using the following command:
fix ins nve_group insert/stream seed 5330 distributiontemplate pdd1 &
massrate 1.0e-6 start 50000 overlapcheck yes all_in no vel constant 0.0 -10.0 0.0 &
insertion_face partIn extrude_length 200e-6
If I do so LIGGGHTS asks me to define either 'nparticles' or 'mass'. I do not see why this is necessary, as to my understanding by massrate, velocity and extrude_length particle insertion should already be defined?
Best

The 'mass' option specifies
The 'mass' option specifies the total mass to be inserted. If you don't plan on stopping the insertion, just use 'mass INF' or any sufficiently large mass.
