You already have it.
Open wingraf and check the results for beam elements and the loadcases 10,11,20,21
MT doesn’t exist since none of your loads generate a twist.
Thank you for the tip. I can find the diagrams in the wingraf.
I also want to see the envelope in the report broswer, below is the code:
PROG
WING
LC
NO
10
BEAM
TYPE
MY
LC
NO
11
BEAM
TYPE
MY
END
But it shows warning:
+++++ warning no. 806 in program gr3_e_stab
BEAM TYPE MY loadcase 10 not valid : No values found
BEAM TYPE MY loadcase 11 not valid : No values found
