EDWRITE, Option, Fname, Ext, --
Writes explicit dynamics input to an LS-DYNA input file.
OptionSets a flag in the LS-DYNA input file (Fname.Ext) to produce desired output.
ANSYS | — | Set a flag to write results files for the ANSYS postprocessors (default). The files that will be written are Jobname.RST and Jobname.HIS (see Notes below). |
LSDYNA | — | Set a flag to write results files for the LS-DYNA postprocessor (LS-POST). The files that will be written are D3PLOT, and files specified by EDOUT and EDHIST (see Notes below). |
BOTH | — | Set a flag to write results files for both ANSYS and LS-DYNA postprocessors. |
FnameFile name and directory path (80 characters maximum, including directory; this limit is due to an LS-DYNA program limitation). If you do not specify a directory path, it will default to your working directory. The file name defaults to Jobname. Previous data on this file, if any, are overwritten.
ExtFilename extension (eight-character maximum).
The extension defaults to K in a new analysis and in a full restart analysis, and to R in a small restart analysis.
--Unused field.
This command writes an LS-DYNA input file for the LS-DYNA solver. EDWRITE is only valid if explicit dynamic elements have been specified. This command is not necessary if the LS-DYNA solver is invoked from within ANSYS, in which case Jobname.K (or Jobname.R) is written automatically when the solution is initiated. (If LS-DYNA is invoked from within ANSYS, use EDOPT to specify desired output.)
If the analysis is a small restart (EDSTART,2), the file that is written will have the name Jobname.R (by default) and will only contain changes from the original analysis.
If the analysis is a full restart (EDSTART,3), the
file that is written will have the name Jobname_nn.K (by
default) and will contain all the information from the database. In a full
restart, the jobname is changed to Jobname_nn (nn =
01 initially, and is incremented for each subsequent full restart.)
A command is included in the LS-DYNA input file to instruct the LS-DYNA
solver to write the results files indicated by Option.
By default, LS-DYNA will write the ANSYS results file Jobname.RST (see
the EDRST command). If Jobname.HIS is
desired, you must also issue EDHIST.
Option = LSDYNA or BOTH will cause LS-DYNA
to write results files for the LS-POST postprocessor. The D3PLOT file
is always written for these two options. If other LS-POST files are desired,
you must issue the appropriate EDHIST and EDOUT commands.
This command is also valid in PREP7.
Distributed ANSYS Restriction This command is not supported in Distributed ANSYS.
