Hello everyone,

I am modelling the filling process of a bottle with water using the inhomogenuous MUSIG model for air entrainment and the AIAD model to differentiate between bubbles droplets and free surface. When starting the simulation I get the error Message:

+--------------------------------------------------------------------+
| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| NAME_MOD: Error finding variable "DIAMCLIP_FL1" |
| |
| |

+--------------------------------------------------------------------+

I searched inside the installation directory of CFX according to this thread:
NAME_MOD: Error finding variable "TSUPER"

I was not able to find the exact variable there. I just found : DIAMCLIP which is a particle diameter.

I assume DIAMCLIP_FL1 would be the particle diameter of one of my fluids (gas or water)? How do I supply the missing variable for the simulation?

Thanks in advance for any help!

CFX error messages are cryptic, and your guesses that it is referring to particle diameters look reasonable. I would suggest it might be looking for a clipping variable on the particle diameters. But exactly what the problem is and how to fix it is not clear.

I would suggest opening your case in CFX-Pre and checking that all the MUSIG and multiphase parameters are correctly set. See if you can find the missing parameter.

I found the solution as I introduced an expression for the Interfacial Area Density using the ccl script:

FLUID PAIR: GasC | Liquid
Surface Tension Coefficient = sigma
INTERPHASE TRANSFER MODEL:
Interfacial Area Density = AD
Minimum Volume Fraction for Area Density = MinVFArea
Option = Particle Model
END


The name was wrong and should be called CLIPPED INTERFACIAL AREA DENSITY.

Has the AIAD model been successfully added to the program?

Mostly, yeah. Do you have the same Error as mine? If not, could you describe your problem?
