Default user subroutines in CFX
Posts: n/a
We want to know whether CFX can

(1) solve incompressible, viscosity flow problem?

(2) add user subroutines for additional equations, variables and special source terms (e.g. surface tension) ?

Thanks in advance.

hi...CFX can do both of them! there are prescribed user subroutines which you can combine and write one of your own to get what you want! cheers... prash

Hi Zeng,

CFX-5 always provides a viscous solution and is equally applicable in compressible and incompressible regimes.

For most applications, additional equations, variables and source terms can be added through the CFX Expression Language (CEL), requiring no programming or additional compilation. Where complicated logic is required, new functions can easily be added to CEL through user subroutines compiled into shared libraries.

For free surface applications, CFX-5.5.1 will include surface tension (CEL can be used to further modify this model, if required). The 5.5.1 release is due out this June.

Best regards, Robin
