topography variation above sinking material

Please login with a confirmed email address before reporting spam

hello,

I am trying to solve topography variation above sinking high viscous material(into viscous medium).

I used "FSI model library", but I always failed.

I think, the effect of sinking material must decrease with depth.

but My model shows the constant effect of sinking mterial on topopgrahy.

Could you tell me something wrong of my model? (e.g. BC)

I attach my model.

please, help me,

I have passed 10 days to try to solving this problem.

thank you
