hi olivertoxoby,

i have a question to a previous email of yours. You wrote (related to case of 2 immiscible fluids):

It wasn't me who wrote this reply - it was @shlxx.

First you create a model of your entire fluid as one geometry (it could be a solid compound, if I understood that correctly) and then a second geometry (for example, a box) which will later be defined in the analysis as a "Initialization Zone". Now you have to start a transient simulation and select multiphase flow. then add two imiscible fluids (such as water and air) then create an initialization zone and define your box as one of the two fluids under volume fractions and set the value to 1 for 100%

I have a question especially to the Statement "create a model of your entire fluid as one geometry (it could be a solid compound, if I understood that correctly) and then a second geometry …". Does it mean that the entire geometry has to be done twice - one time for considering media 1 and one time just for media 2 - and superimpose them ? And meshed twice ?

No, you only create one mesh. There is one geometry for the simulation. However, you have the option to initialise the volume fraction field to a certain value in a certain area if you wish to start with a particular initial distribution of the fluids. You do this with (one or more) initialisation zone(s).
