Hey guys,
Is it possible to have incorrect velocity scaling for slip boundary
conditions? I took an example script (attached) from section "10.10.
Setting up boundary conditions" from ESPResSo online documentation:
http://espressomd.org/html/doc/lb.html
I added the printing of the velocity near the right slip wall and after
reaching steady state it shows almost 100 times larger velocity as it is
supposed to be (0.941 or so instead of 0.01). This behaviour is linked
with lb timestep which was 0.01. Increasing to timestep=0.1 gives only
10times higher velocity.
Could you comment on this?
Many thanks,
Ivan
