Fluid Structure Interaction

Please login with a confirmed email address before reporting spam

Hello, I am trying to model the interaction between an fluid injection and a thin membrane layer. I am unable to get any interaction between the fluid and solid, however. I am using the fluid-solid interaction, assembly to model this flow.

Specifically, I am modeling an injection in between the retina and choroid of the eye. I added a gap in between these two layers filled with the liquid initally to try to simplify the model. I am interested in the deformation of the retina as a result of the injection.

I have tried a time dependent solution but it fails to reach consistent initial values.

The time dependent solution just completely disappears in all of the plots.

Any advice would be appreciated. This is my first time wokring with this interface trying to model deformation and I am just kind of confused even after watching the tutorials. I have attached my COMSOL file below.
