Temperature Loading

Question

Hey !!! 
 
 Can someone help me to use the temperature load, seems somewhat confusing with the f1 f2 terms . What do they mean and how to correctly input these values.

The value (f1) is used by the program to calculate the axial deformation in members or volume expansion in plates and solids due to temp change, 
 The second value (f2) is used by the program to calculate the bending affect due to the temperature change. 
 For inputting these values, 
 You have to know three temperatures : 
 1) the stress-free temperature, or the ambient temperature which you want to maintain . Call it A. 
 2) The temperature of the top fiber (the fiber that is farthest along the positive direction of the local Z axis of elements and local Y axis for members). Call it B. 
 3) The temperature of the bottom fiber (the fiber that is farthest along the negative direction of the local Z axis of element and local Y axis for beam). Call it C. 
 f1 = (B+C)/2 - A 
 f2 = B-C
