User has further option of breaking the user-induced constraints into those DOF constrained by the GRID PS field and those on an SPC set. Answers may be independently filtered to remove smaller SPCForces from the printouts. Resultant vectors for SPCForce contributions are also calculated. Solution Sequence SOL 101. Input Executive Control Include 'spc101a.alt' Case Control Request SPCFORCE output. Bulk Data The following optional parameters control how the SPCFORCES are printed in the output file. SPCLEVEL: Default = 0 (integer). Default will separate SPCForce output into AUTOSPC'd DOFs and modelled-in (GRID/PS plus SPC set) DOFs. Setting SPCLEVEL to 1 will divide SPCForce output into three separate groups: AUTOSPC, GRID/PS, and SPC sets. TINYAUTO: Default = 0.0. Acts as a filter on printed SPCForces for those DOF constrained by AUTOSPC. Any SPCForce smaller in magnitude than TINYAUTO will NOT be printed. TINYSPC: Default = 0.0. Acts as a filter on printed SPCForces for those DOF constrained by either GRID/PS or SPC set cards. Any SPCForce smaller than TINYSPC will NOT be printed. GRDPNT: Default = 0 (integer). Allows user to have SPCForce Resultants summed about this grid point in a coordinate system parallel to the BASIC system. Output Standard solution 101 output plus the ability to separate the SPCFORCES into different categories. Limitations Multiple boundary conditions are not supported.
