Hello again,

I have reduced the time step to 1e-5 and I noticed that it keep running for 4 time steps and I can notice the rotation, but it give me new error. Even if I use laminar option.

Hello,

You still seem to have some zones which are meshed much more finely than the rest.

But more importantly, looking at you distorted cells, it seems some moving cells are "connected" to some fixed cells, meaning that either:

- some cells that should belong to the rotor are not in the rotor selection criteria (check the criteria)

- some rotor cells and stator cells are initially connected (normally, both sets must be disjoint, and connected only during the computation using the criteria defined through cs_turbomachinery_join_add in cs_user_turbomachinery_rotor);

Regards,

Yvan
