Accuracy of Results
I did an analysis of a roughly 12m long assembly. The von Mises stress results came in a lot higher in certain localised areas compared to my traditional FEA solution Simsolid, whereas the overall deflection was virtually the same. To be sure I then ran the same analysis in Simscale whose results corresponded closely to Simsolid. I tried changing connection types and added in some corner chamfers but that did not change the results much. The overall distorted shape looks correct and the deflection corresponds closely to the other FEA's. I wonder if this is a function of the size of the structure and the algorithms used that the local stresses may not be calculated correctly on such a big structure. I know there was an earlier comparison run on a smaller object reported in the forum. Would you please comment? Happy to share the file.
