The panel is launched by pressing the "More Options" button on the main panel.

Job Options

  1. Memory : This option is only available for the MPP/HYBRID version of Ansys LS-DYNA.
    With the MPP/HYBRID versions of Ansys LS-DYNA more memory is required for the first CPU that initialises the model than for the other processors.
    The units used to define the Memory Limit can be switched between Words and Megawords
  2. Memory2 : The value entered is the size of the main array declared internally within Ansys LS-DYNA that is used to store data in.
    The units used to define the Memory Limit can be switched between Words and Megawords
  3. CPU Limit : The value entered is the actual amount of CPU time that Ansys LS-DYNA will use for the analysis.
    When this limit is reached Ansys LS-DYNA will terminate the job.
    The units used to define the CPU limit can be switched between Seconds, Minutes and Hours .
    A value of "0" means that no limit has been set and the job will run to termination.
  4. Output Files : This option controls the names of the output files generated by Ansys LS-DYNA, either ARUP or LSTC can be selected.
  5. CPU Consistency : This option controls whether parallel analyses are run with the accuracy option in Ansys LS-DYNA turned ON or OFF.

Hybrid and Parallel Options

  1. Hybrid Options : Available only for HYBRID LS-DYNA runs on a LINUX machine.
    • MPP/SMP threads : The number of MPP threads that can be selected for HYBRID jobs.
  2. Parallel Options : This option will only be available when submitting MPP jobs.
    • Local Host : When selected the MPP jobs will be submitted using only the machine that the shell is being run on.
    • Node File :This option can be used to select a file containing a list of Nodes and CPUS to use when submitting an MPP job.
      The format of this file is given in the SHELL manual.
    • Node List :This option can be used to specify a string containing the list of Nodes and CPUS to use when submitting an MPP job.
      The format of this file is given in the SHELL manual.

Submission Type Options

The parameters that can be specified under each submission type option are different and those available under the Queue option will vary from system to system.
  1. Start Time : Specify a time at which the Ansys LS-DYNA job will execute.
    • Available for QUEUE or BACKGROUND submissions.
    • The required time should be entered in the form HH:MM using a 24-hour clock.
    • If no time is specified, then the job will be executed as soon as possible.
  2. Start Day : Specify the day on which the job will be executed.
    • Available for QUEUE or BACKGROUND submissions.
    • If a day is specified and no analysis start time has been set, the job will be submitted with a start time of 00:01 on the required day.

Options for QUEUE
These options are available only for the QUEUE submission type.
The options in the menus are prepared from the 'oasys_queue'
  1. Queue Name : NQS style queue list mentioned in 'oasys_queue'.
  2. Queue Options : : The options available will depend on:
    • Selected Queue
    • NCPU value
    • Contents of the 'oasys_queue' file
  3. Queue Memory : The value entered defines the total amount of memory that the job will request from the system.
  4. Queue CPU : The value entered is the total Queue CPU Limit that include the time taken to run the Ansys LS-DYNA analysis and any system time required.
  5. CPU Limit : : When a queue is selected the CPU limit for that queue will be displayed.
    • If the queue is a pipe queue the word PIPE will be displayed
    • If the queue has no CPU limit, then the word NONE will be displayed
