February 20, 2018, 04:39	UDF - How are gradients calculated in fluent ?	#1
annan Member annan Join Date: Nov 2016 Posts: 72 Rep Power: 10	Hello, I would like to know what is the expression of a UDS gradient in fluent. I found in mem.h the following expression : #define C_UDSI_G(c,t,i)C_STORAGE_R_NV(c,t,SV_UDS_I(i)+SV_U DS_0_G-SV_UDS_0) but I can't really understand what it means. Thank you in advance for your answer. DANIELORTIZ likes this.
