fluid/structure interaction (FSI)

fluid/structure interaction (FSI)

(OP)
Has anybody work with fluid/structure interaction(FSI)?
My problem is about an object sinking into the water. I want to model the full sinking of the object into the water. I have created the object (metal) in 3D (solid deformable) with explicit step. the water was created as an Eulerian part.
linear elastic material property was defined for the solid object and EOS (Us-Up) was used to define property of the water.
general contact (all with self) was defined as their interaction.
a load (gravity) was applied on the solid object
a predefined field (mechanical assignment) was defined for the water to apply the volume fractions on Eulerian object.
I have used "Discrete Field" in "Volume Fractions"

the model is running fine with no error but it seams the interaction between the water and object is not working as I can not see any change on the volume of the water when the object is sinking.
does anyone know what is the problem with this model?

RE: fluid/structure interaction (FSI)

(OP)
anyone knows about the examples of fluid/structure interaction?
