T2113

T2113 FATAL ERROR: T2113 CANNOT CHANGE OUTPUT SET WHEN REQUESTING COMBINED RESULTS
Cause: This error occurs when running either PRESTRESS STATIC or PRESTRESS MODAL solutions with PARAM, ADDPRESTRESS, ON specified. ADDPRESTRESS will request that subcase 1 element results be added to subcases 2 through n. When requesting subcase stress/strain output with PARAM, ADDPRESTRESS, ON, each subcase must request the same output set.
Action: Correct the subcase stress/strain output set request or set PARAM, ADDPRESTRESS, OFF.
Remarks: See Autodesk Nastran Reference Guide, Section 3, Case Control, for command format, and Section 5, Parameters, for more information.
