 May 19, 2022, 10:10 Question about copying a single-passage result to the full-passage #1 New Member   Join Date: May 2022 Posts: 5 Rep Power: 3 Hello, everyone. I am doing a fluid-thermal-solid interaction project, linking the CFX model to the static structural model. I compute the solid body temperature in CFX by conjugate-heat transfer, and I import the body temperature to the solid in the static structural model to calculate thermal stress and deformation. And the problem is that I compute a single passage result; for example, I calculate the temperature of a turbine with 21 blades, and I want the whole turbine's body temperature so I can obtain the entire turbine's thermal stress and deformation . Can anybody please help me copy the single-passage result of the CFX to the whole passage？ Thank you so much!

Can you solve the thermal-stress problem with periodic boundaries? It has to be 21 times faster, and less memory __________________ Note: I do not answer CFD questions by PM.

Thank you for your reply. Let me describe this problem more precisely. I want to solve a whole turbine's thermal stress and thermal deformation problem. The period of the turbine rotor is 21, while the period of the turbine stator is 27. I split the turbine stator into two parts; one is the turbine stator forward, and the other is the turbine casing behind. If I use single-passage, I don't know how to transfer the stress and deformation from the casing to the stator; besides, I find out that there seems to be no way to solve the problem of different periods in one model, the static-structural model of the Ansys workbench. And that's why I want to solve the problem in a whole passage.
