Hello everyone, I am using the CFX module in the workbench and the transient analysis module to set up fluid-solid coupling. I set the number of parallel cores in the workbench tool and also set the number of parallel cores in the transient analysis.

For CFX, after I set the number of parallel calculation cores in the solution control of CFX-Pre, CFX prompted the following error:
The Solver Input File value will be ignored when the solver is started as CFX-Pre is within ANSYS Workbench.

However, when I tried to open the solution settings of the CFX module in the workbench main interface, I found that I could not open it directly. So how should I set up the parallel calculation of CFX?

My software version is 2021R2, and the operating system is win11

There are tutorial examples of how to set up fluid-solid coupling simulations in workbench. There are few steps to it so you should have a look at it before starting any of your own simulations.

I reproduced this tutorial, but couldn't find any settings related to my problem.

Did you watch the video you posted? It says that was part 1, in part 2 or the video they set up the coupled analysis. So try part 2 of the video.

Or try the official tutorials which come with CFX. You will find the coupled solver tutorials under workbench (not CFX).

There are three videos in this tutorial, and I have run them all.

Thanks for your suggestions.
