Hi - I am relatively new to Fluent and this forum. Any help would be greatly appreciated and I would be incredibly thankful.

I am trying to model a liquid-filled closed cavity in which the changing in shape of the solid body surrounding the liquid shifts and causes a change in the liquid. The liquid's movement then causes further change to the shape of the solid body. I am attempting this using the System Coupling feature of Ansys. I have completed the structural, solid part of the simulation and am currently trying to model the liquid in Fluent.

When meshing the liquid, I suppress the solid portion of the simulation.

I've created the material and defined the cell zone as the desired material, and I established the boundary condition for the wall as a No Slip Moving wall (the only boundary condition it allows me to edit). I've set the solver to the desired type (Pressure) and Ive also defined a dynamic mesh.

In the Solution tab, I've set the methods to the "coupled" scheme and left everything else as default.

When I click the t=0 initialize button, it tells me in console that initialization is done.

In the Run Calculation menu, I increase the number of iterations.

When I return to workbench and try to update the Setup, it says that "Setup component in Fluid requires user input before it can be updated." I can not seem to solve this issue even after going back through the steps listed above. Is there something I am missing here, or am I simply doing something wrong?

Thank you all in advance.
