Mass fraction imposed
Ver: 0   DESCRIPTION Allows the user to specify the mass fraction boundary condition along a boundary set for the transport equation.

The default value is zero constant.

 
  OPTIONS
-1
 Upper level menu
The value of the mass fraction is accepted
1
 Constant
The current value of the mass fraction is constant on the corresponding boundary line or face
2
 Linear function of coordinates
A linear dependence of the mass fraction upon the current spatial coordinates is selected
NOTES Mass fraction condition is an essential boundary condition for the transport equation. There should be at least one mass fraction condition on the boundary of the domain in order to guarantee uniqueness of the solution.
