hello Yvan, thanks for your help,but I am very eager for your reply. just as you said, when i use the geometry that i uploaded,how can I define the interface?or maybe how can i define the mesh? sometimes I use the conplex geometry,such as the wind turbine with blades,how can I define the interface ?...

Hello, For the Stator and Rotor to join correctly when rotating, you need the interface beween the two to be round, not square. Regards, Yvan hello,Yvan thanks for your reply.i feel grateful to see you reply.but i still feel confused. just as you said, when i use the geometry that i uploaded,how ca...

Hello, Could you post a view of your geometry, showing the rotor and stator parts ? Regards, Yvan hello Yvan, thanks for your reply.Please help me. i don't know how to achive it. i want to know the reason that lead to the erors.so i can check it myself. you can download the "med"and "...

hello,Yvan

this is the "hdf"

hello,Yvan this is my "med". it is a simple case,i just want to know how it works. and the erorrs is that: cs_turbomachinery.c:923: Fatal error. Error in turbomachinery mesh update: Number of boundary faces has changed from 5400 to 6283. There are probably unjoined faces, due to an insuffi...

Hello, You first need to build you own mesh, defining volume groups for the rotor and stator part (so you can define those in the GUI), and one or more groups for boundary faces at the rotor/stator intersection (also used for selection criteria in the GUI). The rotor and stator parts of the mesh mu...

hello Yvan,

thanks for you reply!

Hello, Could you specify what you tried and failed ? I don't think there's a tutorial yet for this feature, but there are quite a few threads on this forum which should help. Are you using the GUI ? It should help guide you. For rotor-stator joinings in transient mode, define the interface faces se...

hello,

I have tried a lot to use the module.but I failed. so can you give me any more details about how to use the module? many thanks.


thanks you,
