Volume fraction in FLUENT

05 April 2012 1 2K Report

how exactly is volume fraction defined in FLUENT,

if volume fraction of a =Qa/(Qa+Qb), then how can this be related to FLUENT

You can use constant volume fraction in the multiphase panel, so that you can the value appears in the bouandry layer conditions panel, but if it is a fonction , you can introduce it by creating an independent file as fluent define it in its help manual and when running the calculation you refer to the file by profile in define panel.

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
