unphysical flow front
 
1 Attachment(s)
Simulating a high viscous fluid that pushes air out of a cell zone I get really unphysical results.

1. My models:

transient, pressure weighted.

VOF (implict, explict divergates)
Energy on and laminar flow.

Using Zone Discretization and the Comprissible Pressure Solver

Methods (as possible) to first order.

Controls Relaxation set to 0,3 (energy to 0.9)


The high viscous fluid should push the air out of the cell zone without building "fingers". Has someone an idea how I could optimize my model?
