SUMTYPE

SUMTYPE, Label
Sets the type of summation to be used in the following load case operations.

MP ME ST PR PRN <> EM DY PP EME MFS

Label

Summation type

COMP

 — 

Combine element component stresses only. Stresses such as average nodal stresses, principal stresses, equivalent stresses, and stress intensities are derived from the combined element component stresses. Default.

PRIN

 — 

Combine principal stress, equivalent stress, and stress intensity directly as stored on the results file. Component stresses are not available with this option.

Notes

Issue SUMTYPE,PRIN when you want to have a load case operation (LCOPER) act on the principal / equivalent stresses instead of the component stresses. Also issue SUMTYPE,PRIN when you want to read in load cases (LCASE). Note that the SUMTYPE setting is not maintained between /POST1 sessions.

SUMTYPE,PRIN also causes principal nodal values to be the average of the contibuting principal element nodal values (see AVPRIN,1).

BEAM188 and BEAM189 elements compute principal stress, equivalent stress, and stress intensity values on request instead of storing them on the results file; SUMTYPE,PRIN does not apply for these elements.
