Hello there,

i am doing a static structural analysis of a containers corner segment on which a force load is applied which represents the wind load.

The problem i am getting is that the equivalent stress distribution across the body is not continuous but is rather ''breaking up'' as seen from the pictures below. Any ideas how could i resolve this problem?

Fixed support is on the bottom side, force is in X direction.

,What do you mean by breaking up? FEA solver calculates the stresses over the elements, and that is what you are seeing. Almost all of the times if you observe something which is not expected, then the problem lies between the inputter (you) and the computer, like loads, materials, goemetry, boundary conditions, contacts. Solver just provides you a solution for the inputs that you have given.
I can just adjust the numbers on stress range such that I would be seeing a continous stress occurring on my structure. So I couldn't understand what you mean by 'breaking up'?
The mesh elements appear to be fine around the regions which are circled by you, so I don't think the stresses that you are seeing is a result of bad mesh quality. It is just how it is supposed to be.

Thank you for the reply @Rameez_ul_Haq, first of all, sorry for the bad description of the problem.
I was expecting the stress distribution to be as continuous as it is on the side where the bolts are.
Yes, as you said, i believe the problem lies somewhere in contacts. But at this point, i'm not sure because i have already tried changing that but the stress distribution looks the same. I have also adjusted the stress range accordingly.
Maybe my expectations were wrong and this is how it is supposed to be.

the ANSYS solver is a wordly renowned and widely accepted software, and its results' accuracy is what makes it the top of the list. They also provide information how they solve the problems for each module that they have, like Static, Transient, Dynamic, etc, in their Help document. So you cannot expect the solver to create any problems while solving because of its internal bugs or something. So if you are not seeing something which you expect, then you most probably are entering something wrong as an input.
