UDF temp. profile BC

Shashikant

hello, I am solving a wall conduction problem steady, I need to give a variable temperature profile on one sid of the wall, I hae gone thr UDF mannual, it can be done using DEFINE_PROFILE but cannot figure out excact code for UDF, the geometry is wall length along X axis. Earlier i have used UDF to define varable property.. .. Can any body show me a sample UDF for temp profile along boundary so that i get the idea ..

thankyou shashi
