Have a look in the user guide and you will see that every property can be easily defined as polynomial function of temperature in the Create/Edit Materials Dialog Box.
If the dependency is more complex, eg. there are logarithmic terms, you will have to use a user-defined-function. Search for Define Property in the udf manual.

cheers

I know about the polynomial function that can be written in properties but in my case logarithmic term is there how to specify that in the equations.

actually sir i dono how to write the UDF can u please help me in this.
