Temperature from previous time step in specific heat UDF -- CFD Online Discussion Forums

October 31, 2013, 10:59	Temperature from previous time step in specific heat UDF	#1
Thomas William New Member Join Date: Oct 2013 Posts: 3 Rep Power: 12	Hello I am using the DEFINE_SPECIFIC_HEAT macro for a Cp relationship based on temperature. I would like to access the temperature from the previous time step. Iv tried C_T_M1(c,t) but it does not work. The purpose is to determine whether the dT is positive or negative, heating or cooling, from which I call different Cp relationships. Any help appreciated. Thank you. Tom
