I don’t know Caesar at all; I’ve used Abaqus before, but I’m not proficient in it either. I’m currently looking at a pipe stress analysis performed using Caesar. I noticed that there are two identical nodes in the Caesar results, and the stress values at these two points are equal in magnitude but opposite in direction; in other cases, the values are not exactly the same. Could anyone please explain to me why this is the case?
Taking an axial force of 40 points as an example, 40 points can be regarded as the dividing point. The axial force between 39 and 40 points is 765 N, which indicates that the ideal unit between 39 and 40 is under tension; the axial force between 40 and 48 points is -765 N, indicating that the ideal unit between 40 and 48 is under compression. It is assumed that positive values represent tension while negative values represent compression.
