Types of Ansys LS-DYNA Executable

 

The radio options to the left of this section can be used to select the desired type of Ansys LS-DYNA executable to used for the analysis.

Precision: Single Precision (32 bit floating point) Double Precision (64 bit floating point)

Code Type: SMP (Shared memory parallel) MPP (Distributed memory parallel) Hybrid

MPI Type: Mentions the "MPI" type of the executable to be used for the MPP Ansys LS-DYNA submission.

Path to the Ansys LS-DYNA Executable

Clicking on these radio buttons will cause the Ansys LS-DYNA Version menu to be populated corresponding to the options specified to be selected.

The submission shell can be used to access more than one version of Ansys LS-DYNA.

Clicking on the menu labeled 'Version' will bring up this drop down menu listing the versions of Ansys LS-DYNA present in the dyna_versions file.

Instead of selecting an executable from the list in the dyna_versions file an executable can be explicitly specified by selecting the 'Local Ansys LS-DYNA Executable' option.

To browse for the executable select the folder icon.

The Precision-type and the Code-type (SMP, MPP or Hybrid) also need to be set to the correct values as it's not possible for the SHELL to know these from just the executable name.

If the code-type is MPP then you also need to set the correct MPI Type.

Default Ansys LS-DYNA Options

The user can also specify a "Default" Ansys LS-DYNA executable related the SHELL preferences.

The "default_ls_dyna_executable" preference assigns the given Ansys LS-DYNA executable path for a given values of the Ansys LS-DYNA type related preferences:

"default_code_type"

"default_precision"

"default_mpi_type"

The user can also specify the path to the MPI executable.

The default MPI executable can be given via the "default_mpi_executable" SHELL preference.

The current selection of the Ansys LS-DYNA executable and MPI executable type and path values can be set as a default into the HOME preference file by pressing the 'Save to oa_pref' button

View/Edit SHELL files

You can also view and/or edit the dyna_versions file and the Oasys.submit file from this section.

If you have the appropriate file permissions you can append the "Local" or the "Default" Ansys LS-DYNA executable related information to the dyna_versions file by pressing the 'Add Version' button.
