Default UDF reading the temperature gradient

Hello,

does anybody know how to acces the z-component of the temperature gradient with an UDF? My UDF works well as long as I define a certain value to the temperature gradient, but when I try it with :

' dT_dz = C_T_G(cell,thread)[3]; '

FLUENT gives me an Error:

' FLUENT received fatal signal (ACCESS_VIOLATION) '

Greetings Fabian

Gradients are not defined at the first iteration. Put that command in an if like this:

if(Data_Valid_P()) { ... }
