Hiya, I am modelling a transient case with two phases, and I would like to know the temperature development of the nodes in a certain thread. I used udf to export the coordinates of the wanted nodes successfully. However, I had some problems when I tried to export the temperature. I defined the field variable name using the following lines:

char *what = "temperature";
Node_Function_Values(d, what);


And I tried to obtain the temperature value using NODE_VALUE(v). But it reports as follows when I tried to print the temperature value.

Error: floating point exception
Error Object: #f


The fl process could not be started.

What is the possible reason which would cause this?

Is it possible that the field variable name that I am using is not right, since it is a multiphase case. How can I know the list of field variable names that I can use in the function Node_Function_Values(d, what); for a multiphase case.

Many thanks for your time.
