Hi there,
I have a multiphase (2 phase) flow of a droplet of a fluid in a flow (domain 2) that eventually leaves domain 1. I want to have the calculation stop when the fluid starts to leave the domain so I created a integration operator to calculate the volume and then a variable that is used in the stop conditions. As the droplet starts to leave the outlet the volume of the fraction of fluid (domain 2) will decrease and I will have the condition stating that when around half of this fluid has disappeared, the study will stop calculating.
Problem is, I am having trouble with the integration operator.
I want it to calculate the volume of fluid for every iteration, so I assume it is dependent upon time. My variable "Vdroplet" (volume of droplet) is defined as intop1(1) in the local variables section and then in the stop conditions stated as Vdroplet<=(an size) then stop.
Would the integration operator calculate the volume every iteration or should it be Vdroplet=intop1(t[1/s])?
Please ask if you need more information and thanks for your help in advance.
