I know I am posting at the wrong place but please try to tolerate me as I am posting here for a purpose(people are more active here).........

I am trying to simulate flapping motion of the wing using Dynamic Mesh. I have setup the case in Fluent but I have some doubts and questions regarding it. I am uploading the pictures which will show the dynamic mesh setup. Kindly tell me is it correct? The problem consist of a domain around the wing, symmetry plane, wing and fluid zones. Few questions......

1. I have declared domain(farfield) as "Stationary" zone as shown in pic1. Is it correct? how to set value of "Cell Height"(shown by a question mark in pic1)?

2. Fluid is set as "Deforming" as shown in pic2. Is it correct? values of the "Zone Parameters" will be taken from "Zone Scale Info" as shown in pic2? right?

3. S1020 is the name of wing which will be given motion using a DEFINE_GRID_MOTION udf and S1020 is set as "User Defined" as shown in pic3 is it correct? how to set value of "Cell Height"(shown by a question mark in pic3)?

4. Symmetry plane is set as "Stationary" as shown in pic4 is it correct? how to set value of "Cell Height"(shown by a question mark in pic4)?

Also after the finalization of UDF I will use full structured hexa mesh for this problem. For this purpose in Dynamic mesh I will only use "Smoothing" and "Layering" for mesh update? am I right kindly comment? I cannot use "Remeshing" as it only works for unstructured meshes? right?

This would have to be a 2-way FSI, I'm guessing you are modeling it that way?

No Its not FSI, I am just solving flow over the flapping wing ofcourse using a dynamic mesh and UDF for the motion of wing.
