Use THREAD_DT(thread), it converts a thread into a dynamic thread.

Exactly the opposite of THREAD_DT(dynamicthread), which converts a dynamic thread into a normal thread.

It's funny that in the Fluent UDF guide (at least the one from 2013 I have) the macro THREAD_DT(thread) appears just once and only in an example. Maybe they don't want us to use it XD
