Interpolation

Interpolation is a feature that allows you to transfer results from a case onto a different mesh.
This is particularly useful when you want to:

- refine the mesh
- run a slightly altered geometry, such as containing flaps
- transition from a BET Disk simulation into a fully-resolved sliding interface simulation for rotors or propellers

New mesh can either exist within the same project as the case or be a part of a different one.
When interpolating, the parameters can be modified, which allows for redefining boundary conditions to match new mesh boundaries.
