I tried to set the lattice velocity to 1/10 but it didn’t work, it still goes quite large at about 10% of the whole time as before. Besides, I didn’t add gravity in this model. It’s just a sphere particle in a rectangular channel with rectangular poiseuille flow.
In addition, I have a lilttle problem of what you mentioned that change the particle’s position before the coupling from the particle to the fluid via couple_particles_to_lattice. Did you mean change the position after couple_lattice_to_particles and before the couple_particles_to_lattice ? I seperate the execute to couple lattice, change postion, couple patcicle. But it still couldn’t work. Could you tell me more details?
Thank you again for answering me!
