Contact Region and Interfaces
 

Hello, I was trying to simulate a Savonius Turbine. I create 2 interface, interface 1 and interface 2 for rotor and fluid domain. However, when I try to mesh it automatically creates contact region and also I am using Parameter Set, so everytime I change the parameter and update it, there is an error about contact region. I want to delete this part and I don't want it to automatically creates new one. How can I do that? Or is there a way to simulate it with parameter set and the contact region?
Thanks for your help.
