Good morning, thank you so much for your availability. Yesterday I imposed different boundary conditions and the rotor started to move without problem but the calculation time is very long. To reduce the error's probability comes I put the time step as 1.e-07. Is it normal? or Do you advice me to reduce the element size?
Here there are some results. Now the calculation is continuing. I am not sure about the spatial discretization (I put all field in second order) and the correction. I have used an UDF to create the mass center of rotor motion. In dynamic mesh I have choosen smoothing ,down there are the parameters and for remeshing I put the size 1 instead of 5. The mesh quality seems in all points good. How can I solve the lackages problem? In real situation the stator and rotor are koined by springs and they can move "up and down" to follow the stator properly but here the 3 chambers are linked.
Thank you in advace.
