Species tab not enabled in boundary condition

SAM S · April 5, 2016, 08:09

Hi, I am using species transport model and volumetric reaction with finite rate mechanism. In the boundary conditions only momentum and thermal tabs are active for use but species tab I couldnt use. What is the problem with my set up. Can anyone please help me.

For what boundary conditions? For inlet boundary conditions, where fluid is entering your domain, it should be active.

Thank you for your reply.
For velocity inlet condition, it is not activated for any of the phases (mixture, phase 1 and phase 2). I am using VOF model. I do not understand why it is not activated. Can you please help me

Hello,
I across with same problem many years after you. I wonder you could fix it. I need the solution if the answer is yes.
