fluent udf, getting fluid density

mohsen zendehbad · January 24, 2010, 03:36

how can we get fluid properties, density and viscocity of the fluid in a udf file?

Hi Mohsen
Are you doing time-dependent simulation? I think I can help you by sending you the C++ udf that I have written for my simulation and explain you how to change it regarding your targets. That will be easy. If you are interested just let me know.

Dear Vandad:
it will be kind of you if you do that. my simulation is both steady and unsteady. I need some short words like C_U or C_V which will return the density or viscosity of fluid in that cell.

Mohsen
pass me your email.
Thanks.

C_R(c,t) - access cell density
C_MU_L(c,t) - laminar viscosity
C_MU_T(c,t) - turbulent viscosity

For more macros read the Fluent UDF manual.
