Hi everyone, i'm new to this board...

the simulation is a simple falling water in a tank under gravity force...

the geometry is a simple rectangular with two regions (it's a 2D mesh)... one on top, which is smaller and it's going to be defined as water. and the rest of the face is air. i want to simulate a transient flow for seeing how water actually falls down...

i define each domain in Basic Settings separately (the top region, Water and the bottom region, Air) but when I check it again, i surprisingly face that two regions are in the same phase!!

the question is how can i apply these settings to be sure that my each domains are in the specified phase that i want?...

it's part of my final project and i really need this help. i hope someone can give me the right direction.

Regards,
Shahed
