Instability with vof with embedded ramp and injection

[Emily Lane]

Hi all,

I am trying to simulate water being injected into a tank with an embedded ramp as a 2D vertical slice VOF, it seems to go okay for a while but then it completely blows up. Does anyone know what I am doing wrong?

I seem to be able to use the embedding okay without injecting something and likewise to inject something without the embedded solid (Although I am less sure of how I am doing that).

Cheers

Emily
