      Hi, this is a simple query. I am trying to figure out how to use expressions to get some calculated quantities. I have a fluid physics region (let's call it "liquid") and I want to calculate what fraction of the volume is at or greater than a certain temperature threshold T0. I used a few combinations of variables and parameters following AIM documentation but I am not able to extract what I need. Any help is appreciated!

      Thanks

      Hello Rahul Mulinti

      You can use the following user-defined expression:

      SumIf(1, Temperature> 300[K],GetPhysicsRegion("@Fluid Flow, Thermal Physics Region 2"),"Volume")

      YOu will have to specify the appropriate name of the physics region from your model, in the above expression.
