I'am simulating a closed model witch is divided in to two sections.
One is filled with air one with an user defined liquid. ( divided by a lid )
I difined two fluid subdomains, which are previewed and shown blue when i click one lid.
I also see the function initial condition where i need to select all the faces which are in contact with the fluid.
What is the diffrence between initial conditions and fluidsubdomains, do i need to set both or does the simulation works fine like i did ?
( Simulation takes ages so i cant just test it )
Thanks in advance !
