Hello,
i am performing a highly non linear metal forming simulation using PAMSTAMP FE simulation software. I have noticed that for the same mesh and boundary conditions, I get different results every time I run the solver.
The model is exactly the same, so what could be the potential causes for differences in the results? Is there some kind of real time influence?
Thanks,
Hamid
When you start a new run, be sure that you have no stored results in your problem. I suppose that you have some stored initial values from previous runs.
Thank you Mohammed for your reply, however there is no stored initial values from previous runs. This problem occurs even if I copy and paste the input files in two different folders, and run them independently.
Many simulations are based on random numbers. In such cases result differs. Are the differences in your results significant?
Yes, differences can vary by up to 10%. Particularly in “thinning“% calculated from the shell elements. They are significant enough to be interfering with my results
