ypchen New Member Yu-Pei Chen Join Date: Jun 2011 Posts: 26 Rep Power: 14	Hi, everybody. My case has a heat flux cross the wall, and it's not a constant value. The value is calculated by integrating the domain from z1 to z2, the variable in the integral is temperature (function of z), others are just some constants. I wanna calculate the integral in UDF. I have a idea by using "TRAPEZOIDAL RULE", but I don't now how to do it. Does anyone knows how to calculate integral in UDF or how to apply TRAPEZOIDAL RULE ?? thank you very much !
