Butterfly Valve Simulation

This is a simulation of the opening and closing operation of a butterfly valve. The calculation is not progressing at all. I would appreciate some advice.

Hi @ishikawa I have checked your project, typically the simulation of the opening and closing operation of a butterfly valve is a CFD simulation to analyze the fluid movement when the valve is either closed or opened. However, you are currently trying to do a linear static simulation, would it be possible for you to let me know what are you interested in investigating?

Thanks!

Thank you for your reply.
I would like to analyze the distortion experienced by the shaft during opening and closing operations, resulting from the interference fit between the seat and the disc.
