I have a transport equation of a scalar C in which it appears another (vectorial) variable i.
Also I have a differential equation of i: div(i)=0. Can I introduce and resolve this equation in Ansys CFX, or it supports only algebraic equations? |

Yes you can add additional transport equations in CFX.

The problem is that I haven't a transport equation, but an additional differential equation to be solved

Well,
![]() If that is the case, you can add and the following Expert Parameters to your simulation: Code:
FLOW: Flow Analysis 1 EXPERT PARAMETERS: solve energy = f solve fluids = f solve turbulence = f END END Cheers |

I have a transport equation of the variable C, in which there is a term containing i; also, I have the equation div i = 0. So, I have a system of two equation. I don't know how I can solve the latter equation

You have four variables (C, ix, iy, iz) but only two equations. Aren't you missing two extra equations to close your problem?

I think you're right! Maybe I need others equations. I will study better my problem
