Nodal data summary

Jose_San_Juan · May 31, 2021, 8:37am

Hi all,

Using the bulk calculator to get max stress on parts I saw the warning “Statistics are based on interpolated data.”.

I then followed the link to What Is the Difference between Cell and Node Data | SimScale). However, when I right-click I don’t see the option “Switch to cell data”.

I then changed to the legacy interface in case it was there and could neither find it. However, I noticed that results for some parts are the same, but some are different (30% higher).

Are these nodal based? How can I get the maximum nodal stress in a part in the new interface?

Hi there. The option to switch between cell and node data should be available for CFD simulations. I am tagging my colleague @ggiraldof here to verify
Cheers!

Thanks for looping me in @tsite

In FEA, all the results are node-averaged, and delivered directly from the solver. This is why it is not possible to switch to cell (element) data in the post-processor.

Did you find that the results are different between legacy and beta post-processor, for the same simulation run? Can you please provide me the URL to an example of this?

Thanks for your answer.

The images above are taken from

In particular they belong to Von Mises for Part 1 in Run 2.

As you can see, max/min are different but average is the same.

Hi Jose,

You are right, and there is something strange happening here.

The new view’s bulk calculator should be more precise and reliable, but it is strange that the legacy is showing a higher stress value. I reported this to our dev team and they are investigating on the issue. I will update you with their findings.

Thanks for taking the time to report this, this is much appreciated.

Thank you for looking at the issue.
