edrun

Mapdl.edrun(option='', cons='', ncpu='', **kwargs)

Specify LS-DYNA serial or parallel processing.

APDL Command: EDRUN

Parameters:

option

LS-DYNA processing option

SERIAL - Use serial processing (default)

SMP - Use Shared Memory Parallel processing

cons

Consistency setting (only applicable when Option = SMP)

0 - Result consistency is not required (default)

1 - Result consistency is required

ncpu

Number of processors to use (applicable only with Option = SMP)

Notes

The EDRUN command specifies either serial (one CPU) processing or shared (multiple CPU) memory parallel processing (SMP). When using SMP, the calculations may be executed in a different order, depending on CPU availability and the load on each CPU. You may therefore see slight differences in the results when running the same job multiple times, either with the same number or a different number of processors. Comparing nodal accelerations often shows wider discrepancies. To avoid such differences, you can specify that consistency be maintained by setting CONS = 1. Maintaining consistency can result in an increase of up to 15 percent in CPU time.

並列処理の設定は、複数のCPUと適切な数のANSYS LS-DYNA SMPタスクのライセンスがある場合にのみ有効です。この2つの要件を満たしていない場合は、コマンドの設定に関係なく、EDRUNコマンドでシリアル処理が設定されます。

For more information on using SMP, see Solution Features in the ANSYS LS-DYNA User's Guide.
