PLOT XY_

bespel — Fri, 14 May 2021 14:18:15 GMT

Hi,
can you help me to understand what I miss with the XY plot?

-Non Linear analysis, 20 increments, Intermediate Output=All

For incrementent 1 >> I have at the extreme of the bar 4,02 mm
incrementent 6 >> I have at the extreme of the bar 24,15 mm
incrementent 20 >> I have at the extreme of the bar 80,49 mm

If I try to use the XY plot with node (extreme vertex), and Multi Set (Start Set INCR1 and End Set INCR20)
And Result Data as Displacement, with the above numbers I would have expexted a curve..something but a line.

Then click Show XY Plot...
But I have this and it seems to me not aligned with the above numbers.
Here to version of the results:

Same strange results if I use Element and Solid Von Mises for Result Data (at the base of the bar).
I should have a curve with low stress at INCR1 and max stress at INCR20

What Am I missing?

Attached the file.

Thanks!

Hello @bespel ,

Are you using a comma (,) as a decimal separator and a point (.) as a digit grouping symbol?

Change the decimal separator to a point (.) and make sure that the digit grouping symbol is a comma (,).

You are a genius @Roelof.Feijen !!

Many thanks!

What do you think about this tricky issue?

I think that it's quite a shame that for a normal users it's request to do this to make Nastran work.

Am i the first in the world with this?

And now, in 2021..still no fixed?

Am I free to have and keep my setting in Windows or Do I have to follow no-sense-tricky rules to make work a tricky software?

What about 1 day with 8 users blocked on this stupid issue?

We will get the anser neither in 100 years alone. No sense in this.

Really quite a shame. Nastran needs to be updated. We are in 2021, wake up!

(It was not for you @Roelof.Feijen , obviusly, you has been GREAT!).

It is not the first time I see this issue. Not only with Nastran. In the past I have seen other FEA software with the same issue. I agree, this should be fixed.
