Hi @ilovenili

The flag `solve/iterate` is merely to control the solving routine of the adapter. This routine then has the reading, writing, advancing, and other necessary steps in one solution step of the coupling. Therefore this is not an error, but just a simple way to control the time loop and make the coupling logic more accessible.

You do not need to explicitly realize reading, writing, and advancing. This is done inside the adapter. To set up a fluid-structure interaction scenario where Fluent is the fluid part, look at the [adapter README](https://github.com/precice/fluent-adapter/blob/develop/README.md) for instructions.

thank!  
by the way,I’ve posted some requests for help these days, but I feel like the service team might be too busy and haven’t gotten a response, so if you have the time, could you take a look for me?
