UDMI error when memorizing Dissipation of TKE -- CFD Online Discussion Forums

June 23, 2005, 10:59	UDMI error when memorizing Dissipation of TKE	#1
Lohen Guest Posts: n/a	Hello, I am saving the dissipation of TKE in a UDMI thanks to C_UDMI(cell,thread_l,1) = C_D(cell,thread_l); in my UDF concerning the modification of the drag coefficient. If I compare the value from the UDMI and the dissipation calculated by Fluent, the two values are different, the UDMI one seems to be around half of it. Does someone have an explanation !?? Thank you !
