Problem with fix move/mesh command

Submitted by Zakia on Thu, 05/18/2023 - 16:47

Hi,
I am trying to run a FT4 simulation where an impeller is rotating and moving downwards. The issue is I am getting similar force with different speeds. Has anybody faced anything like that? Can someone help me with that please?
The commands that I am using is:
#rotate the impeller
fix move1 all move/mesh mesh mesh_impeller rotate origin 0.0 0.0 0.0 axis 0.0 1.0 0.0 period ${i_period}
fix move 2 all move/mesh mesh mesh_impeller linear 0.0 0.0 -0.00875

any help would be greatly appreciated.

Thank you
