initial volume -- CFD Online Discussion Forums

April 11, 2011, 18:26	initial volume	#1
wlt_1985 Senior Member raymond Join Date: Nov 2009 Posts: 149 Rep Power: 16	My model consists of initial volume domain, Vro. Additional volume, Vadditonal will added into this initial volume domain during time flow. Hence, the final volume, Vfinal will be Vro + Vadditional. I would like to calculate my initial domain, Vro when time flow=0 in my UDF for further calculation. I found that total volume +=C_VOLUME(c, t) is work for Vfinal as time flows. However, I do not know on writing UDF in calculating the Vro. Anyone please help me to solve my problem. Thanks a lot. Best regards
