LSDYNA

LS-DYNA
Description: Suite of programs for transient dynamic finite element program
SHARCNET Package information: see LS-DYNA software page in web portal
Full list of SHARCNET supported software

Introduction

Before a research group can use LSDYNA on sharcnet, a license must be purchased directly from LSTC for the sharcnet license server. Alternately, if a research group resides at a institution that has sharcnet computing hardware (mac, uwo, guelph, waterloo) it maybe possible to use a pre-existing site license hosted on an accessible institutional license server.

Usage

These usage instructions apply to the module based installation of lsdyna found under directory /opt/sharcnet/lsdyna on licensed clusters shown in the above Availability Table. To access and use this software you must be a member of the lsdyna group. Users who belong to a licensed department will be given a 5 digit port number. The value should then be inserted into the appropriate departmental export statement before loading the module file as follows:

o UWO Civil and Environmental Engineering Dept

export LSTC_LICENSE_SERVER='PortNumber'@license1.uwo.sharcnet

o McGill Mechanical Engineering Department

export LSTC_LICENSE_SERVER='PortNumber'@license2.uwo.sharcnet

o UW Mechanical and Mechatronics Engineering Dept

export LSTC_LICENSE_SERVER='PortNumber'@license3.uwo.sharcnet

Module Selection

[roberpj@orc-login1:~] module avail lsdyna
 
-------------------------------------- /opt/sharcnet/modules ---------------------------------------
lsdyna/ls971mpp6.0.0 lsdyna/ls971mpp6.1.1 lsdyna/ls971smp6.1.0 lsdyna/ls980mppB1
lsdyna/ls971mpp6.1.0 lsdyna/ls971smp6.0.0 lsdyna/ls971smp6.1.1 lsdyna/ls980smpB1

o For serial or threaded jobs, using ls971 do:

module load lsdyna/ls971smp6.1.1

o For mpi jobs, using ls971 do:

module unload intel openmpi lsdyna
module load intel/11.1.069 openmpi/intel/1.5.4 lsdyna/ls971mpp6.1.1

o For serial or threaded jobs, using version ls980 do:

module load lsdyna/ls980smpB1

o For mpi jobs, using version ls980 do:

module unload intel openmpi lsdyna
module load intel/12.1.3 openmpi/intel/1.4.5 lsdyna/ls980mppB1

Job Submission

To run the single or double precision solvers specify lsdyna_s or lsdyna_d respectively:

o SUBMIT 1CPU SERIAL JOB

sqsub -r 7d -q serial -o ofile.%J --mpp=2G lsdyna_d i=airbag.deploy.k ncpu=1 

o SUBMIT 4CPU SMP JOB

sqsub -r 7d -q threaded -n 4 -o ofile.%J --mpp=2G lsdyna_d i=airbag.deploy.k ncpu=4

o SUBMIT 4CPU MPI JOB

sqsub -r 7d -q mpi -n 4 -o ofile.%J --mpp=1G lsdyna_d i=airbag.deploy.k

Example Job

STEP1) The following shows a sample sqsub jobs submission for the airbag example to the mpi queue shown in this link http://www.dynaexamples.com/examples-manual/misc/airbag where you I suggest first changing endtim to 3.000E-00 in airbag.deploy.k to the job runs long enough to perform all steps in this section:

cp -a /opt/sharcnet/lsdyna/ls971smp6.1.1/examples /work/$USER/test-lsdyna
cd /work/$USER/test-lsdyna/misc/airbag
gunzip airbag.deploy.k.gz
module unload intel openmpi lsdyna
module load intel/11.1.069 openmpi/intel/1.5.4 lsdyna/ls971mpp6.1.1
export LSTC_LICENSE_SERVER=#####@license#.uwo.sharcnet
cp airbag.deploy.k airbag.deploy.restart.k
sqsub -r 1h -q mpi --mpp=4G -n 8 -o ofile.%J lsdyna_d i=airbag.deploy.k

STEP2) With the job still running, use the following echo command to trigger generation of restart files at which point the file D3KIL will vanish as described here http://www.dynasupport.com/tutorial/ls-dyna-users-guide/sense-switch-control:

echo "sw3" > D3KIL

STEP3) Now either manually kill off the job or wait until it exceeds the -r time limit:

sqkill job#

STEP4) Before the job can be restarted, the following two lines must be added to the airbag.deploy.restart.k file:

*CHANGE_CURVE_DEFINITION
         1

STEP5) Now resubmit the job as follows using "r=" to specify the restart file:

sqsub -r 1h -q mpi --mpp=4G -n 8 -o ofile.%J lsdyna_d i=airbag.deploy.restart.k r=d3dump01

General Notes

Checking Job Status

To check the status of your job in the queue use the sqjobs command. On x86_64 systems you can check whether any of your jobs are queued on the license server use lstc_qrun. Its possible that sqsub will start your job but it will sit idle until enough license are available on the license server and the lstc_qrun command will reveal this:

Checking License Details

At the time of this writing UWO is running on a 4cpu demo license as follows:

Legacy Version Instructions

The following binaries remain available on saw and orca for backward compatibility testing:

[roberpj@orc-login2:~] cd /opt/sharcnet/local/lsdyna
[roberpj@orc129:/opt/sharcnet/local/lsdyna] ls ls971*
ls971_d_R3_1    ls971_d_R4_2_1  ls971_s_R3_1    ls971_s_R4_2_1  ls971_s_R5_1_1
ls971_d_R4_2_0  ls971_d_R5_0    ls971_s_R4_2_0  ls971_s_R5_0

There are currently no sharcnet modules for these versions, hence jobs should be submitted as follows:

module load lsdyna
export PATH=/opt/sharcnet/local/lsdyna:$PATH
export LSTC_LICENSE_SERVER=XXXXX@license3.uwo.sharcnet
cp /opt/sharcnet/local/lsdyna/examples/airbag.deploy.k airbag.deploy.k
SERIAL JOB:  sqsub -q serial -r 1d -o ofile.%J ls971_d_R4_2_1 i=airbag.deploy.k
THREADED JOB:  sqsub -q threaded -n 4 -r 1d -o ofile.%J ls971_d_R4_2_1 ncpu=4 para=2 i=airbag.deploy.k

Note! the ls971_s_R3_1 and ls971_d_R3_1 binaries do not work, a fix is being looked for.
