f := struct.node.temp.increment(sn)
struct.node.temp.increment(sn) := f

Get/set the the temperature increment that will be applied to the structural node in the next timestep, causing elements connected to it to see changes in stress due to thermal expansion. This value is cleared to zero after every step when thermal expansion stresses are applied.

Returns:f - temperature increment
Accepts:f - temperature increment
Arguments:sn - structure node pointer
