I am conducting a spring design analysis using Hyperworks (Hypermesh, Radioss, Hyperstudy, Hyperview). For the moment, I already have a database of previous analysis done by previous researchers. After I ran one simulation using the same input parameters as the previous study, I noticed that I obtained a slightly different results.
So my question is, is it possible to have a different result despite having the same input parameters? Is there any result consistency with regard to the Radioss solver? What could possibly go wrong?
