Hi All,
Good day to you.
I am currently working on a flatbed chassis design. I want to determine the maximum stress in the beam under desired loading condition.
I've run the simulation two times, exactly the same properties, and it give two different result. Could anyone care to help me on this?
Thanks in advance.

Attached the related image. beam web was 4mm thick, top and bottom flange are 10mm thick with 180 width. material tensile strength is 750MPa while yield strength is 700MPa. Elastic modulus is 205GPa. Load per item is 294300N and the fixture is at the highlighted blue area in picture above.
oh almost forgot, the first run give max stress about 625MPa while second run give 1250MPa.
Can you screenshot the loads and constraints for each case? Did the mesh change?
Hi Fahmi,
It seems strange that the stress has exactly doubled... Did anything change between the runs, materials, loads etc.?
Would be good to get the actual files as it is likely just a set-up problem rather than a solver problem.
Cheers
Steve
..or better yet - the actual data set.
Have you got some screen shots of how you set each up and what the results were?
