solver stops when erosion should be starting?

So, I'm making a model in Flow 3D, about the final stages of placing a skirted GBS on the seafloor (1.5m above seabed till 0m above seabed). The z=0 line is at the surface of the sand. The BGS has a downward velocity of 0.2 m/s.
The problem I have, is that the solver stops when the skirt tip touches the seabed. Normally erosion should start here (or some seconds before the skirt hitting the seabed) because there's still water inside the skirt before the GBS reaches the sea floor.
Here's what I did so far:
- I have the scour model activated, with a set critical shields and 1 particle diameter
- I also activated viscosity and turbulence RNG model, with a constant mixing length of 0.0001.
- My soil is set to packed sediment.
