mark multiple region in multiphase flow in fluent

rishabhgupta · February 10, 2016, 06:53

Hello friends, I am simulating the flow of Taylor bubbles in stagnant fluid in slug flow. I have successfully simulated with single bubble. But now with multiple bubbles I facing problem with marking multiple bubble region. please guide me how to do this.

Thank You

adapt region -> mark several (!) zones for your bubbles, then go to "manage" inside adapt region window and use the "combine" function to combine your regions into one new combined region. now you can use this combined region to patch your bubbles in solution initialization window

you can also realize more complex regions to patch via udf (google patch region udf or something, there are also some examples in the manual), but for simple geometries adapt region window is fine
