TICTV User’s Reference Manual Bulk Data Entry TICTV Defines translational velocity initial conditions for the structural model for Direct or Modal Transient Response analyses. Format and Example: 1 2 TICTV -cont- SID TICTV 3 4 5 6 7 8 9 10 CID A V1 V2 V3 GID1 -cont- GRID ID LIST 1000 THRU 1 10.0 1.0 0.0 0.0 1 3399 Field Contents Data Range Default SID Set identification number. [1,2] Integer>0 Required CID Coordinate system identification number in which V is defined. Integer≥0 0 A The value of translational velocity. Real Required Vi Components of a vector, in coordinate system CID, defining the direction of translational velocity. Real 1.,0.,0. GID1, Initial GRID point, and list of one or more GRID points, which will have velocity initial conditions computed. Integer>0 Required GRID ID LIST Remarks: 1. Transient initial condition sets must be selected in the Case Control packet with the command: IC = SID Initial conditions are the sum of all data from TIC, TICRV, and TICTV Bulk Data entries. 2. 3. Initial conditions for components not specified on TIC, TICRV, and TICTV entries are assumed zero. Therefore, if an IC command is not present in the Case Control packet, all initial conditions are assumed zero. Options on the Case Control command IC may be used to cause the automatic calculation of initial conditions when applie loads are non-zero at t=0. Also, initial conditions may also be computed automatically for Modal Transient Response analyses using Bulk Data entry PARAM,NRB. UAI/NASTRAN BULK DATA 7-381 7 BULK
