Hi,
I am doing multiphase simulation in a single domain for fluid(water)/pipe/fluid(clay) interaction. I consider free surface homogeneous model. The pipe has a sinusoidal movement i.e. initially it placed in water and then will move into the clay.
I am getting the following message:
+--------------------------------------------------------------------+
| ****** Notice ****** |
| Evaluation of quantitative CEL functions on mesh regions use |
| conservative values even if the mesh regions coincide with a |
| boundary condition region |

And

ERROR #002100004 has occurred in subroutine Out_Scales_Flu. |
| Message: |
| The Reynolds number is outside of the range expected based on the |
| Option selected for the TURBULENCE MODEL. Check this setting, |
| the values of the properties, mesh scale, consistency of units |
| and solution values in the input file. Execution will proceed.


The run has finished normally but after post processing I am getting a jagged interface between water and clay all the way around even very initially(at time step zero). Please see the attached file at time step zero.

Can anybody help me for the above, especially the last one (interface mixture), why this happen and what is the theory behind it?

Thanks in advance!
