3.14 Restart Parameters
This format of the Analysis form appears when the Action is set to Analyze and the Object is Restart. Currently, restarts are only supported for the Linear Static (101), Nonlinear Static (106), and Normal Modes (103) Solution Sequences. Linear and Nonlinear Static jobs can be restarted as Linear or Nonlinear Static. Normal Modes jobs can be restarted as Frequency Response, or Transient Response. The DBALL and the MASTER files for the initial job must be present in the current directory when the restart job is submitted.The Restart Parameters button on the main analysis form allows the user to enter information about where to resume the analysis. The Patran Analysis Manager User’s Manual contains more information on how to submit restart jobs with Analysis Manager. Restart for SOL 600 jobs are described on (p. 307) and (p. 451).
Linear Static/Normal Modes
This subordinate form appears when the Restart Parameters button is selected on the Analysis form and the solution type of the initial job is Linear Static or Normal Modes.
Nonlinear Static
This subordinate form appears when the Restart Parameters button is selected on the Analysis form and the solution type is Nonlinear Static.
SOL 600
This subordinate form appears when the Restart Parameters button is selected on the Solution Parameters form.
Parameter
Description
Restart Type
You can Write restart data, Read restart data and Read and Write restart data. The default is None for no restart data.
Create Continuous Results File
If, when restarting a job, you wish the results form the previous run to be copied into the new .t16 file, then turn this ON. Otherwise MSC.Marc will not copy the results to the new .t16 file. If you turn this ON, you must have a restarname.marc .t16 and/or restartname.marc.t19 file in your local directory or the MSC.Marc analysis will fail.
Last Converged Increment
Writes a RESTART LAST instead of a RESTART option. ON by default.
Reauto
OFF by default. This places a REAUTO option in the MSC.Marc input file. Any additional data needed for the REAUTO option are extracted from the first Subcase information for the restart job. Only if the Restart Type is set to Read or Read and Write is the REAUTO written or the toggle visible to the user.
Restart from Increment
Defines the increment to be read from the file specified in the Select Restart File form. It is only requested when Restart Type is set to Read or Read and Write. The last increment on the restart file is used for the RESTART LAST option when Last Converged Increment is ON.
Increments Between Writing
Defines the number of increments between writing data to the restart file. It is only requested when Restart Type is set to Write or Read and Write.
Select Restart File...
This brings up a file browser to select the restart file when the Restart Type is set to Read or Read and Write.
