Programming turbulence models (CFX 4.4)
 
Hello, I'm programming some turbulence models with the fortran USR interface of CFX 4.4

I read that there are "dummy cells" used internally by CFX to model boundary conditions (e.g. for walls).

It would be usefull to use these cells in my turbulence models as well, but I don't know how to adress them or work with them.

I would appreciate any hints concerning that topic.

Thanks in advance.

CALL IPALL('*','WALL','PATCH','CENTRES',IPT,NPT,CWORK,I WORK)

DO 100 I=1,NPT

INODE = IPT(I)

IBDRY=INODE-NCELL

IACTIVE=IPNODB(IBDRY,1)

IDUMMY=IPNODB(IBDRY,2)

....... Dummy cell is stored in IDUMMY, active cell in IACTIVE. Hope this helps Fabian
