Dear all,
I try to understand coupling in an assembly mode by using Laminar flow+Solid or Laminar flow+Mutlibody dynamics module. To do this, I'm following a easy task which is pipe(water) + sphere(iron) model. I am able to achive following,
- Cylindrical body for pipe
- sphere body for iron
- run this model in union mode or assembly mode (laminar flow physic active only)
When I add solid or multibody dynamics module and choose "Fluid-Structure Interaction, Pair" then my model does not work unless I fixed every boundaries of sphere. Identity boundary pair is created automatically and I use it under multiphysic section. Whatever I do and read the manuals + other applications carefully, I did not face with a solution. Please see the figure
Any suggestions ?

Dear Huseyin,
It is difficult to suggest anything without seeing the model or exact error message. Please contact COMSOL support for any help you need in order to model this problem.
Best regards,

Dear Pawan,
Thank you for your response. Could you please provide me laminar flow+solid mechanics application at least ? One I find is fixed at one point in 2D.
