hi I m supposed to simulate two-phase laminar flow problem (moving mesh).
the size of a cyl is ,
r=5 h=5
The bottom of the cylinder is fixed and the top of the cylinder is moving with a certain speed in normal direction.
the side face of the cyl. is exposed to the air.
geometry
cyl : r=5 h=5
material water
physics
wall at h=0 : no silp and predescribed mesh velocity =0
wall at h=5 : moving wall u=0.01 m/s and predescribed mesh velocity=0.01m/s
r=5 external fluid interface predescribed mesh velocity inactive
the error mesg. :
remeshing fulfilled for initial time. or last time step of newton method is not converged.
singularity problem..etc
help.
