Volume fractions problem for multiphase flow

ENSAF · July 23, 2019, 06:02

Dear all,

Actually, I'm simulating a multiphase flow composed of three phases on ANSYS Fluent. I'm using a 3D geometry, and I define the characteristics of each phase.
when I try to set the initial volume fraction I have this message :
" Warning!! The sum of phase volume fractions exceeds 1 in some faces(s).
This can lead to potentially erroneous initialization. Please insure that the sum of phase volume fractions on a face does not exceed 1 during intitialization or patching!! "
can you help me please!

Thank you

Regards
