Dynamic mesh for transient FSI simulations

      I want to do transient FSI analysis of sloshing using System-coupling module. Whether it is 1-way or 2-way FSI, is it necessary to define a "dynamic mesh" and create the fluid-structure interfaces to be "system-coupling"...??? 

      If not defined, will it effect the result...??? 

      Please clarify this doubt of mine. Thanks in advance...

Thank you Mr.kkanade,


                I am encountering certain errors while trying to run a 2-way FSI using System coupling - 


Here are the pictures of my simulation -


1. Geometry



2. Fluid mesh




3. Fluent settings



4. Structural mesh




5. Structural analysis settings



6. System coupling settings






7. Error




Thanks is advance...

as your shape of domain changes, due to motion on boundaries, you will have to define dynamic mesh.
