Can wemodify effective thermal conductivity by UDF -- CFD Online Discussion Forums

October 26, 2005, 23:09	Can wemodify effective thermal conductivity by UDF	#1
FengYun Guest Posts: n/a	In Phoenics CFD software, we can modify effecive thermal conductivity in energy equation by adjusting the thermal diffusivity. I want to know if we can do the same thing in FLUENT by UDF. The DEFINE_DIFFUSIVITY macro is not possible because it only can be used to specify the diffusivity for the species transport equations or user-defined scalar (UDS) transport equations. Thanks a lot.
