Hi,
I am modeling some shell for my thesis and I got double results in some points, after runing the calculations.
Some times I am getting two values with different sign.
How can I interpretate this values?
Thanks
After obtaining the result I got double values in some points, what does it mean?
Hi @Anonymous
You have generated automatic combinations SLS and ULS. When combinations envelope is selected SLS+, SLS- or SLS Combinations (the same for ULS) and maps description is on, values for top and bottom envelope are presented.
You will have single description for single load cases selected.

Hi Krzysztof, thanks for your answer.
I understand that I should have an envelope only for moments but why do I have and envelope in Normal forces?
Shouldn’t I have only one force?
And which value and combination should I choose for designing: ULS, ULS + or ULS -?
Lastly is yellow colour in compression (positive value) and blue colour tension (negative values) the in the shell elements in Robot.
Please find attached my file.
Thanks
