hello. gud morning to all.......sorry to ask this dumb question. im just new to caesar.

i did a stress analysis for a burried piping and here is the report;

RESTR REPORT: Loads on Restraints
CASE 1 (OPE) W+T1+P1

NODE Fx Fy Fz Resu.Force Mx My Mz Resu.Moment Restraint Type
lb lb lb lb ftlb ftlb ftlb ftlb

100 -1097 14 7254 737 0 0 0 0 Bi-linear X2
100 522 0 79 528 0 0 0 0 Bi-linear X2
100 0 0 0 0 0 0 0 0 Bi-linear X2

The questions are:
Why there are three nodes reflected in the reports. What are these forces?

I also noticed that the resultant forces are always positive eventhough there are negative forces.


Hope you could help me with this, many thanks.
