Convergence of statistical moments

UQ with UQLab Community Q&A and How To

Hi,
I implemented the convergence plots method using PCE for the estimation of the statistical moments. I am little suspicious whether or not this convergence plots seemed normal?
Looks like I am unsure here how to attach a figure. Can you give me some guidance? Thank you!
Best regards

Dear Visha

You can either copy and paste your figure or upload it using the Upload button found in the taskbar when you create a post.

Hi,
Now I got it, here is the plots I got from my model. It seemed strange that the convergence happened pretty quickly. One I have simply by plotting the total indices from Sobol analysis for 5 uncertain inputs and another from the PCE statistical moments convergence.

Thanks for your inputs!
