Taylor bar example#
This example is inspired by the “Taylor Bar” example on the LS-DYNA Knowledge Base site. It shows how to use PyDyna to create a keyword file for LS-DYNA and solve it within a Pythonic environment.
Perform required imports#
Import required packages, including those for the keywords, deck, and solver.
import os
import pathlib
import shutil
import tempfile
import ansys.dpf.core as dpf
import matplotlib.pyplot as plt
from ansys.dyna.core import Deck, keywords as kwd

mesh_file = DownloadManager().download_file(
mesh_file_name, "ls-dyna", "Taylor_Bar", destination=os.path.join(EXAMPLES_PATH, "Taylor_Bar")
)
Create a deck and keywords#
Create a deck, which is the container for all the keywords. Then, create and append individual keywords to the deck.

Memory size from command line: 20000000
on UNIX computers note the following change:
ctrl-c interrupts ls-dyna and prompts for a sense switch.
type the desired sense switch: sw1., sw2., etc. to continue
the execution. ls-dyna will respond as explained in the users manual
type response
----- ------------------------------------------------------------
quit ls-dyna terminates.
stop ls-dyna terminates.
sw1. a restart file is written and ls-dyna terminates.
sw2. ls-dyna responds with time and cycle numbers.
sw3. a restart file is written and ls-dyna continues calculations.
sw4. a plot state is written and ls-dyna continues calculations.
sw5. ls-dyna enters interactive graphics phase.
swa. ls-dyna flushes all output i/o buffers.
swb. a dynain is written and ls-dyna continues calculations.
swc. a restart and dynain are written and ls-dyna continues calculations.
swd. a restart and dynain are written and ls-dyna terminates.
swe. stop dynamic relaxation just as though convergence
endtime=time change the termination time
lpri toggle implicit lin. alg. solver output on/off.
nlpr toggle implicit nonlinear solver output on/off.
iter toggle implicit output to d3iter database on/off.
prof output timing data to messag and continue.
conv force implicit nonlinear convergence for current time step.
ttrm terminate implicit time step, reduce time step, retry time step.
rtrm terminate implicit at end of current time step.
