# How to obtain stress result by combining symmetry and anti symmetry result

Pioneer

Hi all,
I have read the user guide about how to use the combination of symmetry and anti symmetry result to simulate load on only half of a structure. Please read article from the link below

However it only shows how to get the displacement result but it does not show how to manipulate the stress result. Does anyone how to do it?

Thank you very much

In a linear solution sequence, this linear combination of results is valid for all results types. Simply add additional output requests under the SUBCOM case control. I.e. to include stresses and strains, simply use the following:

```\$
TITLE = SYMMETRIC AND ANTISYMMETRIC
SUBCASE 1
LABEL = SYMMETRIC CONSTRAINTS - Y LOAD
SPC  = 1
\$
SUBCASE 2
LABEL = ANTISYMMETRIC CONSTRAINTS - Y LOAD
SPC  = 2
\$
SUBCOM 3
LABEL = LEFT SIDE OF MODEL - Y LOAD
SUBSEQ 1.0, 1.0
DISP = ALL
STRESS = ALL
STRAIN = ALL
\$
SUBCOM 4
LABEL = RIGHT SIDE OF MODEL - Y LOAD
SUBSEQ 1.0, -1.0
DISP = ALL
STRESS = ALL
STRAIN = ALL
\$```
