How can I validate a simulation result?

Suchart Jaisue Oct 14, 2014 11:42 PM

I did a simulation of structural analysis by linear elastic with isotropic condition and compared the results between Solidwork and Ansys.

I found that the results were different, the magnitude of stress/strain by using Solidwork was lower than Ansys around 5 times but stress/strain distributions of them were in the same trend.

Could I know how to validate a simulation result between these two program

5 times off is way too much. Is it a very complicated structure, perhaps with a lot of no penetration contacts? Can you show a picture?
How did the displacement compare? Stress/Strain is more affected by mesh size so start by comparing displacements.

inside the software there are validation problems to use as a starting point

i'd say you have some kind of unit problem if something is 5 times off
