Problems with circular shapes in FSI simulations

I am working on a impact model of the human head. Skull, Cerebrospinal fluid (CSF) and the human brain.
First I made a very simple model without the brain. Just a simple square filled with the CSF. There is a force applied (starts at 3e-5 seconds ends at 9e-5 seconds ) at the front of the square which represents the impact.
BUT when I model the brain in this square (see it as a circle in a square, around the square is the CSF) the simulation stops always at the timestep when the force will come up.
I tried all different kind of meshes and it didn't help. Maybe the problem is the density of the brain and the fluid, because they are almost simular??
end time = 3e-3
time step = 3e-5
Hope someone can help me.
