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 ?
