Transferring Distribution of Flow Variables

How to transfer distribution of a flow variable (or a combination of flow variables) from one solution to another for the same geometry without affecting data in the 2nd solution?

You can transfer distribution of a flow variable from one solution to another for same geometry with the following steps:

1. Copy required data in a UDS
2. Write interpolation file with UDS data only
3. Interpolate UDS onto the 2nd case/data
4. Define CFF
5. Copy into UDM for further manipulation using CFF in patch initialization, if needed
