Hi, I need to define an Addititonal Variable, function of this variable itself, i.e.:

Var = Var + 1

I can do it but I can not initialize the variable so the solver gives errors!!!

How can I do that with CCL in CFX-PRE?

Many thanks

Hi Stex,

If you write this as an expression, you will get an error. If you actually create an algebraic additional variable, you can initialize it as you do velocity, temperature, etc.

Where in ccl editor?

FLOW: DOMAIN: hot

FLUID MODELS:

ADDITIONAL VARIABLE: mshot

Additional Variable Value = mshot + (30*(projMassFLow-MassFlow)/projMassFLow)

Option = Algebraic Equation

END

END END END

or

FLOW: INITIALISATION:

Option = Automatic

INITIAL CONDITIONS:

Velocity Type = Cartesian

CARTESIAN VELOCITY COMPONENTS:

Option = Automatic

END

STATIC PRESSURE:

Option = Automatic

END

TEMPERATURE:

Option = Automatic

END

END END END

Hi stex, Did you find a solution? I have the same problem with initialization of an additional variable based on an algebraic equation.
