Negative Pressure at flow front with VOF model

Hello,
I'm trying to simulate the flow of plastic mold with high viscosity through carbon fibres in a 2D. Therefore I'm using the VOF-Multiphase model.This is similar to the flow around cylinders. The problem is, that after very few time steps there is a very high negative pressure near the flow front. I've tried many different solution methods and boundary conditions but nothing seems to make the solution better. Has anyone ever had the same Problem or any idea how to solve it? Thank you in advance for your help! |
