global forces and moments

dear all,
can someone tell me about output results in ceasar.. there are two things about forces and moments at particular node, i.e. "RESTRAINT SUMMARY" and "GLOBAL ELEMENT FORCES". actually i have seen im my result all values in both cases are same but there are some difference in FX and FZ value. for example at any "+Y restraint", the value of "FY" is same in both cases, but "FX" and "FZ" values are not same. can u please tell me reason behind this. i searched in technical reference guide also. but i m not getting the answer

The Global Force Report gives you the forces and moments acting on the pipe element - essentially the free body diagram.

The Restraint Report gives you the forces and moments acting on the restraint, which may be the combination of the loads from multiple elements.

I think the difference in your results are due to friction, which on a +Y restraint has components in the X and Z-directions.
